Abstract
There is a great demand for the portable IR camera on pyrovidicon (PV) to solve the problems of diagnostics and non-destructive testing. This imager allows to watch low temperature objects having their own radiation. Temperature changes which are caused by the image of the heat radiating object of PV, create corresponding potential distribution, which is considered to be a scanning electronic beam. The main advantage of the camera of PV is comparison with the other means which are intended for the work in IR field of spectrum does not need to be cooled. Electron beam scanning is carried out by the focusing-deviating system which consists of the magnet deviating system and magnet focusing system. A drawback of the existing standard IR imagers is in their low resolution of camera, great geometrical deviations of the formed image and comparatively big weight. The ways of IR camera (IRC) perfection on the basis of PV are considered and great attention given to the new design of focusing- deviating systems - the main unit of IRC. It should allow the decrease of weight and size geometrical distortion, power consumption and increased resolution.
