Nowadays, mirrors and lenses are used that have surfaces with a deep asphericity of rotational symmetry, and there is a strong need for the precise shape measurement of these surfaces. It is not easy to measure this kind of surface by using the common interferometric method becatm the fringes are too dense to be observed. For decreasing the fringe number, a radial shear method1 is adopted.© (1987) COPYRIGHT SPIE--The International Society for Optical Engineering.

A multiplex hologram is synthesized by using a special optical system from an original film composed of a series of conventional photographs taken from different horizontal directions. An automatic apparatus for synthesizing multiplex holograms is built and fundamental properties of reconstructed images such as distortion and resolution are studied for both ordinary and medical objects. Some techniques to compensate the distortion are developed.© (1985) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.

A cylindrical holographic stereogram (CHS) is synthesized by using a series of photographs which have only the horizontal parallax, and the reconstructed image has distortions. Images reconstructed from a CHS of laser reconstruction (LCHS) and a CHS of white light re-construction (WCHS) are calculated under various conditions, and the optimum conditions for making and viewing the LCHS and WCHS are studied.
