The invention discloses a composite optical sensor. The composite optical sensor comprises an optical sensor and a polygonal mirror which is arranged above an optical imaging lens of the optical sensor and used for reflecting incident rays onto the optical imaging lens of the optical sensor, and the imaging surface of an image sensor in the optical sensor is divided into a plurality of nonoverlapping imaging areas so as to form a plurality of virtual observation view fields. The invention further discloses a realization method for the composite optical sensor. With the composite optical sensor and the realization method in the invention, the size and the weight of the composite optical sensor are maximumly reduced, and power consumption of the composite optical sensor is decreased; automatic navigation and positioning can be realized when the plurality of observation view fields are used for respective imaging of fixed stars and near-earth objects; and when the plurality of the observation view fields are used for imaging of multiple fixed stars in a plurality of view fields, a huge observation view field is formed, and star pattern recognition can be carried out.
Description
technical field [0001] The invention relates to the optical sensor technology in the field of satellite autonomous navigation, in particular to a compound optical sensor and its realization method. Background technique [0002] At present, all countries are developing various satellite autonomous navigation technologies that do not rely on ground radio measurement and control, in order to improve the satellite's autonomous operation, autonomous management and on-orbit survivability. With the development of manned spaceflight and deep space exploration technology, the requirements for autonomous navigation capability of spacecraft are more urgent. [0003] The autonomous celestial navigation system uses optical sensors to observe celestial bodies. Commonly used optical sensors include star sensors, sun sensors, infrared horizons, ultraviolet earth (moon) sensors, and planetary cameras. The system usually uses a combination of multiple optical sensors to determine the space p...
