Development of Short-Wavelength Infrared Vidicon.
Abstract
The original scope of the program was the exploratory development of infrared vidicons using nickel(I)-doped germanium cooled to 65K as a photoconductor. The unsuccessful attempts to attain the proper doping of the sensing layer are described and the reasons why the approach was abandoned are given. The scope of program was switched to the improvement of infrared vidicons using copper(II)-doped germanium cooled to 77K as a photoconductor. The preparation of these sensing layers and detailed processing schedules are described. The successful implementation of a reticulation process yielding increased resolution is outlined and its limitations are described. The performance and construction of the tube are discussed and an analysis of the theoretical sensitivity of both the photoconductor and the vidicon is presented. Measured performance data of two tubes fabricated under this contract are given and their performance is compared to the theoretical limit. Recommendations for future work are made. (Author)
