Abstract:

The Night Vision Sight, Individual Served Seapons, ANPVS-4, amplifies the low light level illumination of the night sky i.e., starlight, moonlight reflected from the object and its background to form an erect, clearly defined image. The primary component of the sight is the image intensifier tube. The tube operation is such that a light image focused on a photoemissive cathode by an objective lens causes the emission of electrons in direct proportion to the light energy falling on each unit area of the cathode. The electrons are accelerated and focused by the high-voltage electron optical system and travel through the microchannel plate, which multiplies the electrons and impinge on a phosphor screen providing a highly intensified image of the initial low-light-level image falling on the cathode. The eyepiece magnifies the resultant image and presents it to the human eye. High voltage for the tube is provided by a battery-operated power supply.
