SATELLITE SPECTROPHOTOMETER FOR ENVIRONMENTAL MONITORING

摘要

The invention relates to a satellite spectrophotometer for monitoring the environment. It is applicable to remote satellite methods of research of the atmosphere. The satellite spectrophotometer for environment monitoring consists of holy protection aperture (1), located in front of the flat scanning mirror (2) with the reference placed in the source (3), that serve the photometric and spectrometry tract and represent input-scanning system, operated by the stepper motor (22), which through gearing (23) is connected mechanically to the scanning mirror (2) and electric with photoelectric converter angle-code (24) for the implementation of the feedback. Against the scanning mirror (2) on the same optical axis is located a concave mirror (5), and between them is mounted rigidly reflecting Prism (4) guiding part of the optical signal to the spectrophotometer tract, and the other part to the photometric system of the spectrophotometer. The concave mirror (5) from the spectrophotometer tract is optically flat mirror related (6), which in turn-over entrance diaphragm (7) and by a concave mirror (8) is connected with diffraction grating (9) mounted on a mobile carrier (10), and from her Chamber lens (11) and diaphragm (12) to output- -sensor (13). Flat mirror (14) by photometric tract is linked via optical lens (15), an interference filter (16) and optical lens (17) with sensor (18). Sensors (13 and 18) respectively from spectrophotometer tract and photometric tract are connected electrically to the microprocessor system (MVS) (19) through the respective analog-digital converters (ADC) (20 and 21). The stepper motor (25) by means of a mechanical block (26) is connected mechanically to the carrier (10) using a grid (9), and photo electrical angle-code converter (27) is connected to the electric motor (25). Optical signals from reflecting prism (4) enters in semi transparent flat mirror (14) in the lens of the video camera (28) after the microprocessor system (19) registers an information signal over a certain level.
