In this article, the authors used a thermochromic material, cuprous mercuric iodide, to record an on-axis interference pattern, which was subsequently reduced in a two-step photographic process, and reconstruction was accomplished in the visible with He-Ne laser light.Abstract:
Infrared holography at 10.6 μm has been accomplished by using a thermochromic material, cuprous mercuric iodide, to record an on‐axis interference pattern. The pattern is subsequently reduced in a two‐step photographic process, and reconstruction is accomplished in the visible with He–Ne laser light.read more

Infrared holography using the thermochromic material Cu 2 HgI 4
J. M. Yang,Donald W. Sweeney +1 more
TL;DR: Thermochromic materials can be used to record infrared holograms at 10.6 microm as has been demonstrated by others, and theory shows that a resolution of 50 l/mm can be attained.

Mid-IR and terahertz digital holography based on quantum cascade lasers

TL;DR: In this paper, a combination of quantum cascade laser (QCL) sources and a high-resolution microbolometric camera is used for IR digital holography. But the QCL emission covers several windows throughout a large portion of the IR spectrum, from the mid-IR to the terahertz region.

Holographic Method of Measuring Scintillation Effects
Paul H. Deitz,J. M. Evans +1 more
TL;DR: By this technique both amplitude and phase information in a two-dimensional cross section of a received optical beam are recorded and the mode structure of the source is not seen to be critical in this application.

Statistical Theory of Superlattices
TL;DR: In this paper, the effect of fluctuations in configuration, which was neglected by Bragg and Williams, was taken into account, which is similar to that used in Weiss's theory of ferromagnetism.

Magnification and Third-Order Aberrations in Holography*
TL;DR: In this article, the authors derived formulas for angular, lateral, and longitudinal magnification in reconstructed images by holography (imaging by reconstructed wavefronts) and discussed conditions under which one or more of the aberration coefficients vanish, taking into account an off-axis angle of both reference and illuminating beam.
