Infrared imaging system

摘要

A pair of scanning mirror systems scans an object image in two dimensions over an infrared detector. The detector signal and signals proportional to the position of the mirror systems permit display of an image of the object on a video monitor. The video monitor display includes a portion thereof which is an image of the object and another portion thereof which is a temperature profile curve of the infrared intensity across one line of the image. A memory is optionally employed to store a frame of video information and to replay it at a much faster rate than it is scanned in order to form a persistent image on the video monitor. Automatic brightness control circuitry adjusts the displayed signal level according to the maximum temperature of the object being imaged.
