Abstract:

Efforts were made to fabricate a device that will continuously transform infrared images into visible reproductions. Converters which utilize the photoconductive process, in general have high sensitivity, high speed of response and spectral characteristics which are intrinsic to the particular photoconductor. This type rather than one based on the thermal principle or the photoemissive principle was selected. The tube proposed utilizes a photoconductor sensitive out to 40 microns and a photoemitting surface sensitive in the visible portion of the spectrum. Characteristics of this tube are described. The proposed tube has all the advantages associated with Vidicon operation, plus the additional advantage that a wide variety of photoconductors can be used, whose resistivity is not suitable for Vidicon conversion. The pilot tube has demonstrated the validity of the image conversion concept.
