Abstract
PURPOSE:To obtain an infrared image pickup device of low power consumption, by using a rotary scanner of a square column form having a small windage loss by cutting off the square part of the ridge caused at the intersection of mutually adjoining planes over the entire length or partly. CONSTITUTION:The rotating position of a rotating polygonal column scanner 4 which is formed by cutting off the square parts of the ridge caused at the intersection with the plane of reflection is detected by a scanner position sensor 10 to produce a position signal, which is divided down by a frequency divider 11, and a sawtooth wave to drive a galvanometer 13 to oscillate a plane scanner 5 is generated in a sawtooth wave generator 12. On the other hand, an infrared ray beam 1 passing through an afocal system 2 is scanned by scanners 4, 5, and focused into an infrared ray detector 7 by means of a detector lens 6. The output from the detector 7 is amplified into a video signal 14 and is synchronized with a synchronizing signal generated in a synchronizing signal generator 15 on the basis of the output from the sensor 10. Then the signal is processed in a signal processing part 16 so as to be suited for display, and is displayed in a display part 17 as a picture image.
