Abstract

PURPOSE:To make it possible to miniaturize a unit and also to reduce its power consumption in addition to the improvement of sensitivity by using a high-speed scanner of mechanical two-dimentional scanner for a vertical scan. CONSTITUTION:The fitting directions of prismatic-polyhedron rotary mirror 2 and vibrating mirror 4 and changed by 90 deg. and mirror 2 is used for a vertical scan while mirror 4 is used for a horizontal scan. In this case, the visual field of mirror 4 increases to increases its needed amplitude, and a parameter concerned with mirror 2 is greatly improved. Namely, when the aspect ratio (of the vertical visual field to the horizontal visual field) is 4:3, product mn (m is magnification when an infrared telescope employs an afocul system and n is the number of angles of mirror 2) is allowed until a value 4/3 the conventional one and, therefore, the temperature resolution is (3/4)<1/2> time when a parameter except product mn is the same, improving the sensitivity.
