Abstract
Abstract This invention relates to devices for detecting images of invisible radiations and reproducing them as visible images. These devices are provided with detecting means which upon irradiation by a beam of invisible radiation carrying the image of the examined body exhibit various ''''optical'''' changes. These changes are analyzed in a scanning mode point after point by a monochromatic light beam which after recombination with nonmodulated part of said monochromatic light beam provides readout information about said invisible image. This scanning readout is characterized by means providing the same angle of incidence of light beams on all successive points of said detecting means. The above readout information is received and subsequently converted by photoelectric means into an image. In another embodiment of this invention instead of scanning readout means are provided to produce simultaneously a plurality of combined monochromatic light beams for simultaneous readout of said optical changes. It is also characteristic for this embodiment that photoelectric means receive said plural combined light beams simultaneously.
