Abstract

PURPOSE:To obtain high reflectances with only one sheet of reflecting surface and maintain the distinctness of images by providing an off-axis parabolic mirror as the detector optical system of the infrared ray image pickup device condensing the infrared rays which the target object radiates. CONSTITUTION:The infrared rays 1 which the image pickup target radiates are captured with an afocal system 2 as incident light and said rays are scanned horizontally by a rotary polyhedral mirror 4, after which the rays are vertically scanned with a vertical scanner 5 in synchronization to a fixed partial period, by which the infrared rays 1 from each instantaneous field of vision are converted to parallel luminous fluxes 1'. Here, an off-axis parabolic mirror 6 is provided and the parallel luminous fluxes 1' are condensed to the infrared ray detector 7 placed in the focus of said mirror. The output of said detector 7 undergoes video amplification 8 then signal processing 9 and forms the video in display 10. The use of one off-axis parabolic mirror in this way necessitates only one sheet of required polishing surface and enables high reflectances virtually free from wavelength dependency to be provided and the images to be made distinct.
