Infrared detector device for the exploration of thermal images by systems operating a scanning of the parallel series type with the relative manufacturing process

摘要

Disclosed is a parallel/series infrared scanner for detecting thermal images. "N" infrared detecting elements are arranged in series to scan a single portion of an I.R. image. Adjacent portions of the I.R. image are scanned by additional elements also arranged in series but parallel to the "N" series of elements. The specific detector elements can be selectively activated in order to compensate for disuniformity among detectors in the series. Thus, it is unnecessary to utilize precisely identical infrared detector elements because the number of activated elements in a single series can be adjusted to provide a uniform output which is precisely matched to the output of the other series of detectors.
