Abstract

PURPOSE:To improve the reliability of a scanning type stereoscopic sensor as well as reduce the power consumption and costs with a simple and light weight structure, by providing a rotary scanning mirror having a reflecting surface inclined with respect to the rotation axis, and disposing reflecting mirrors on the optical path observable by a sensor disposed on the rotation axis. CONSTITUTION:A sensor 4 such as an infrared detector or the like is disposed on the rotation axis X of a rotary scanning mirror 3 having a reflecting surface 6 inclined with respect to the rotation axis X. Reflecting mirrors 1, 2 are disposed on both sides of the rotary scanning mirror 3, thereby to make it possible to obtain scanning lines (a) and (b) an visual angle beta rear or front with respect to a scanning line (c) on the surface of the earth to be detected by the sensor 4 through only the rotary scanning mirror 3. An artificial satellite equipped with such stereoscopic sensor senses the surface of the earth as shown by an arrow F. The height of an object is calculated from the observation time difference between two points on the surface of the earth by means of the reflecting mirrors 1, 2. Thereby, the reliability of the scanning type stereoscopic sensor is improved and the power consumption and costs are reduced with a simple and lightweight structure.
