    Abstract: LASER-INTERROGATED HOLOGRAMS PRODUCED IN SILVER HALIDE EMULSIONS BY AN ETCH-BLEACH DEVELOPMENT PROCESS HAVE DESIRABLE PROPERTIES OF LIGHT DIFFRACTION EFFICIENCY BUT ARE SUBJECT TO RAPID LOSS OF DIFFRACTION EFFECTIVENESS OVER PERIODS OF EXPOSURE TO HIGH ENERGY DENSITY LEVELS OF INTERROGATION LGHT. IT HAS BEEN FOUND THAT POST-DEVELOPMENT HARDENING, ESPECIALLY BY SUCCESSIVE APPLICATION OF A HARDENING SOLUTION AND HEAT CAN PROLONG EFFECTIVENESS HALFLIFE BY A CONSIDERABLE FACTOR. THE HEATING STEP IS MOST EFFECTIVE WHEN CARRIED OUT IN VACUUM OR INERT GASEOUS ATMOSPHERE.

    Abstract: Interference pattern recording is accomplished by simultaneous holographic and Lippmann holographic methods by directing the otherwise wasted radiation of the noninformation modulated beam back into the storage medium. Interference again takes place with the information-bearing beam to form another image in the medium. After processing the medium, reconstruction of the stored information is performed and a substantially stronger output image is generated.

    Abstract translation: 通过将非信息调制光束的其他浪费的辐射引导回存储介质中，通过同时全息和Lippmann全息方法实现干涉图案记录。 信息承载梁再次发生干涉，以形成介质中的另一图像。 在处理介质之后，执行存储的信息的重建，并且产生相当强的输出图像。

    Abstract: INTERACTIVE PROJECTION DISPLAY SYSTEM An interactive projection display system having a light pen device for use thereon is described. The projection display system has an image of a light valve on a projection screen which is formed by visible light of specified wavelengths. The projection screen also has a translatable crosswire image thereon which is formed by radiation which includes the visible light used to form the light valve image and an additional spectral component. The light pen device is sensitive to this additional spectral component. In a preferred embodiment, the image of the light valve and the crosswires are formed with white light (0.3 to 0.7 microns). The additional spectral component used for the crosswire image and the light pen sensing is a band of near-IR radiation (0.7 to 1 micron).
