Abstract

physical regularities of hologram interferogram and speckle pho. tographs recording on photothernioplastic recording media depending upon exposure re''erence. . to. object ratio charge current recording temperature and other paranieters have been found0 A possible application of simultaneous photothermoplastic process in stroboscopic and double. . exposure holographic interferometry averaged holographic interferometry on continuous and pulse Qswit ched lasers has been shown. . 14ost of the known speckle. photographic techniques for displacement control and image processing have been carried out on phototherrnopla. stic carriers i. e. : double and xnultipleexposure speckle. photogra. . phy speckle photography of moving objects subtraction coding image multiplexing etc. 1. E1RIivENT SET Holographic interferograms (HI) were recorded in continuous heli umneon and ruby pulsed lasers field according to a standard outof. axis Leith Llpatnieks scheme. The Presnel correlation scheme was em ployed in the device for the dynamic control of HI and hologram re- 286 / SPIE Vol. 1238 Three-Dimensional Holography: Science Culture Education (1989)
