Research and Development of Low-Light-Level/Near IR Camera Tube with Solid-State Array Target.
Abstract
The research and development on a low-light-level/near infrared TV camera tube with a solid state array target was divided into three major tasks: (1) a literature study and theoretical evaluation of feasible target structures, (2) development of selected target structures, and (3) assembly and test of exploratory camera tubes. Primary performance objectives were a broad spectral response and high quantum efficiency with IR sensitivity extending beyond the capabilities of silicon vidicons. Other design objectives were low dark current, moderately high resolution, and adequate signal integration capabilities. A number of diode type target structures were considered, viz., Ge homojunctions, Ge-GaAs and Ge-Si heterojunctions and Ge homojunctions with a passivating GaAs film on the scene surface of the target.
