ABSTRACT:
This camera comprises an electron tube with a photosensitive target (6) made of single-crystalline semiconducting material, lens (10) for forming the image of a scene on the target, an electron gun (14) to supply an electron beam to read the target, and scanning and focusing portion (18) designed to force the target to be scanned by this electron beam and to focus this electron beam on the target. The target then outputs a signal representative of this image. The camera also includes an electronic processing circuit (20) for controlling the electron gun and scanning and focusing of the camera and receiving and storing circuits (22) for receiving and storing the signal. Application to the analysis of very fast movements.
