Abstract

The ability to translate digital images into photo-recordable images is one characteristic of a light valve. It is now becoming evident that resolutions will be achieved in this process which will match the resolution capabilities of the normal eye. Thus the spatial light modulator can play a key role as a transducer between digital memories and the user who wishes this information to be presented in a graphical, real world format. The advantages of a light valve which does not have a particular pixel structure, i.e. photoactivated light valve, are many. Newer input scanning techniques are moving to the point where small compact structures are becoming feasible. The challenges between a raster scanned structure and an x-y matrix scanned structure represent two extremes. The raster scan addressing requires an increasingly high bandwidth video amplifier. The x-y matrix address requires an outstanding number of perfect address lines and drive transistors. It is likely that a linear array of LED's scanned in one dimension, will be the preferred configuration for very high quality output. Photoconductors, especially composite phototransistor configurations, allow the expansion of the response of a given device well into the best output wavelengths of LED's. This class of device, parallel drive in one dimension and scanned in the orthogonal dimension begins to display the real capability of the optical computing nature of these light valves.
