Introduction to the Special Issue Honoring Professor Emmett Leith

by

James D. Trolinger, Guest Editor

 It is a great honor to have this opportunity to organize and edit this special issue honoring the man who profoundly affected the lives of so many scientists, engineers, and artists who refer to ourselves as holographers. In planning the issue, the most difficult task was selecting a few from the thousands of people who could have and most probably would like to have contributed. Our goal was to include a broad range of contributors, from the art, science, and commercial arenas, whose lives had been touched deeply by Emmett, to include students, co-workers, friends, and admirers of Emmett, and to draw from all over the world, showing the extent of his influence. At the same time we also demanded high quality technical reporting of new knowledge that would show how the field Emmett created is thriving and continues to provide fruitful applications. 

 Finding contributors was not difficult; everyone I invited expressed both a desire and an obligation to honor this great man. The resulting list of contributing authors includes some of the most widely respected holographers in the world, from eight different countries, and completely satisfies our original goal.

 Professor Yury Denisyuk, another giant in the field of holography and a dear friend had heartily agreed to contribute an article to honor his friend, Emmett. He had submitted preliminary ideas for the paper including preliminary writings on which it would be based. Unfortunately, he became ill before he could complete the work and passed away almost exactly six months after the death of Emmett Leith. After considerable thought we decided not to include his incomplete work, knowing that he would have insisted on near perfection for such a paper.  Instead, I include a picture of Emmett and Yury together in Boston, taken on the day of the death of Steve Benton whom they had come to honor.  

 Emmett mentored some of the greatest minds in holography, even before he became a full professor with students of his own. Ken Haines (Canada/USA) and Karl Stetson (USA), two of the best-known names in holography, are examples. Ken gives his impression, based on first hand knowledge and from many discussions with Emmett and his associates, about what the group actually accomplished, hoping to clarify some of the misconceptions that have arisen in the history of holography. Ken sums up his feelings about Emmett with the following: “….., I always came away feeling that he was one of the finest people I had ever met. Although he was a scientific giant, I remember him most not for his scientific achievements, but for the kind of person he was”. Similarly, Karl gives his first hand account about the history of holographic interferometry, one of the most important scientific applications of holography. Brian Hoover (USA), a more recent student of Emmett’s, writes about extracting modal information from unresolved targets.

 Others who worked directly with Emmett were quick to develop a respect and appreciation of both the man and the scientist. Francis Yu (USA) emphasizes the relative importance of Leith’s contribution and confirms what is essentially a universal agreement among contemporary holographers that Emmett should have shared the Nobel Prize with Dennis Gabor.

 Vladimir Markov (Ukraine/USA) shows how lasers and holography interacted and fed upon each other, concluding that holography is more a phenomenon than a method because so many other fields like phase conjugation benefited from being understood from a holographic viewpoint. This notion is reinforced by Oliver Bimber (Germany) in a discussion of the interaction of holography and electronic displays and graphics. From the world of art, Andrew Pepper (England) reassures us that holographic art is still alive and well, though a bit more matured and less hyped as a novelty than it was in earlier times.

 Applications of holography cover an extremely wide spectrum today.  John Watson (Scotland), Fernando Mendoza-Santoyo (Mexico), Ichirou Yamaguchi (Japan), and Anand Asundi (Singapore) report on different applications of the most advanced form of holography, digital holography, which grew naturally out of basic holography. John hosted Emmett’s visit to Aberdeen University where he was granted an honorary Ph.D. 

 

John Caulfield and Jian Fu (USA) describe another state of the art application of holography in spectroscopy, while Armando Albertazzi (Brazil) describes an application in residual stress analysis, illustrating the diversity of the applications of holography. Tobias Haist, Susanne Zwick, Michael Warber, and Wolfgang Osten (Germany) describe the use of spatial light modulators in recording holograms, illustrating how recording media for holograms have evolved from the extremely tedious photographic materials to fully electronic media, opening the way to programmable, dynamic holography.

 I am proud to be associated with these authors, and I believe that Emmett would have enjoyed reading the papers they have contributed in his honor.

Discussion with Professor Leith in Boston, Nov, 2004

Emmett Leith, Father of modern holography,  passed away on 23 December, 2005, one day before his official retirement started.

I have agreed to act as guest editor for the Journal of Holography and Speckle to create a special issue of the journal in October, 2006. I will attempt to assemble some of the best holographic scientists in the world from as many countries as possible to create an issue that will honor Emmett in a way he deserves to be honored. We owe a great deal to this genius, who was not just a great scientist. He was a great man.

Title: Algorithms in speckle-pattern interferometry for recognition of vibration modes on unresolved targets

 Most laser measurements of complex vibrations are made either by scanning a focused probe beam over the target or by imaging the target. These measurement formats are however precluded in certain scenarios, for instance when the target is beyond the resolution limit of the optical system. In this investigation derived speckle correlations among harmonics of continuous-wave heterodyne power spectra are applied to the recognition of low-order vibration modes on an unresolved flat target. The target is represented by a set of harmonic pistons of common frequency and arbitrary complex amplitude, each of which produces a Gaussian speckle pattern. A graphical mode-recognition algorithm is based on the derived result that adjacent harmonics in power spectra due to targets with zero integrated vibration are uncorrelated. The algorithm is applicable over a range of vibration amplitudes, relative to the wavelength, dependent on the target structure, discrete or continuous, ultimately limited by detector signal-tonoise ratio, and for continuous surfaces extendable with signal-processing steps enabled by sophisticated hardware. Sampling guidelines for continuous target surfaces are demonstrated computationally.

Title: Holographic Spectral Image Discrimination and Segmentation

 How holograms can be used to produce "Artificial Color filters" that accomplish exquisite spectral discrimination with much better sensitivity and cost than comparable means such as hyperspectral imaging. This is an extension of holographic spectroscopy in which the spectrum is allowed to have both positive and negative components.

Title: Circle of Holography – Digital In-line Holography for Imaging, Microscopy and Measurement

 Gabor proposed the concept of holography for wavefront reconstruction. The advent of the laser enabled Leith et al to develop this concept into a technology with off-axis holography. Advances in computational methods and better digital recording medium, holography is starting anew with Gabor holograms. In this paper we discuss the principles and applications of digital in-line holography and its applications in Imaging, Microscopy and Measurement

Title: Measurement of surface shape and position by phase-shifting digital holography using dual wavelength
 

A new method for measuring both the shape of a diffusely reflecting surface and 3-d position of a point on the surface is proposed.  We employ an in-line digital holography with phase-shift of the reference beam to calculate the conjugate product of the complex amplitudes which are recorded before and after wavelength shift of a laser diode and reconstructed numerically.  The surface shape is obtained from the phase of the product, while the position from the CCD recording holograms is derived from the reconstruction distance that maximize the product averaged locally.  The resolution for the surface shape is a few tens of micrometers and that for the position amounts to a few percents of the object distance.  Physical explanations are given on the basis of speckle displacement.

Title: 3D Pulsed Digital Holography for the Measurement of Static and Dynamic Events

A study of the optical and theoretical mechanisms to obtain 3D displacement data from a rectangular coordinate system will be presented. Information is individually separated into the x, y and z displacement  components, that may be used to calculate a variety of physical parameters such as strain, and in some cases used to find inhomogeneities within semi solid materials.

Title: Dynamic Holography for Improved Laser Capabilities

 

This paper discusses a new paradigm in performance of laser systems with dynamic holograms. When used as an intra-cavity element such a hologram enables hybrid laser architecture. Among other distinctive features, this hybrid architecture allows for such effects as coherent coupling of laser cavities, coherent beam combining in a multi-channel laser, an automatic tracking of remote targets.

Title: When did creative holography die?

When news about Emmett Leith’s work in Holography was published in Scientific America,  in 1965,  it had a remarkable impact.  It was one of the first ‘general’ articles about the process which captured the interest, and imagination, of artists.  This paper will offer a brief overview of the involvement  of artists in holography, their contribution to the field during the past 40 years and highlight current creative activities.  An answer to the title’s question will be given.

Title: Merging graphics and holograms
This article outlines how display holograms can be combined with interactive computer graphics. Digitally projected light is used for replaying the holographic content synchronized to the rendering of autostereoscopic or stereoscopic graphics. Modifying the local intensity of the projected light beam allows creating consistent occlusion and shading effects between both – graphics and hologram. This, however, requires depth information of the holographic recording. While flatbed scanners are suitable for estimating surface depth of small to medium size white-light holograms, range scanning is preferred for large-scale holograms. While the integrated graphical elements allow interactivity that is not supported by analog display holograms, the holograms can provide a visual quality that is not possible with today’s three-dimensional displays.
