A technique of three-dimensional imagery has been developed, as an extension of the Gabor wavefront reconstruction process. The image produced is essentially a reconstitution of the original scene and exhibits many of its visual characteristics: parallax between near and more distant objects, a requirement to refocus the eyes when viewing objects in different parts of the scene, and finally, a three-dimensional effect equal to that obtained by ordinary stereo photography.

A network of sixteen stations has been established in the Midwest to obtain photographic data on bright meteors. Special photo-electric techniques have been devised to automate the camera stations, which continuously patrol the nighttime sky.

Much significant diagnostic medical data exists in image and photograph form. To expedite the analysis of this data, the medical profession has begun to look to digital computational methods for greater efficiency. In this paper, the photographic electronic, and optical problems related to the design of input devices for this kind of data processing equipment will be discussed.
