Abstract

The technical scheme of the invention discloses an optical calibrating system and an optical calibrating method. The calibrating system comprises a reflecting and transmitting unit, a total reflectionunit and a light sensing unit, wherein the reflecting and transmitting unit receives a light beam and transmits the reflected light beam to form a transmitting light beam; the total reflection unit receives the transmitting light beam and reflects a total reflection light beam or a pull back light beam, an included angle is formed between the total reflection light beam and the transmitting lightbeam, and the pull back light beam pulls back along the transmitting light beam; and the light sensing unit receives the total reflection light beam or the pull back light beam to determine a spot coordinate of the total reflection light beam or the pull back light beam. According to the technical scheme, the measuring efficiency is improved, the measuring duration is shortened, and the reliability and consistence of measured data are improved.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to an optical calibration system and a calibration method. Background technique [0002] The laser beam is widely used in the field of measurement due to its strong directionality, extremely small divergence angle, narrow beam, and highly concentrated energy in space and frequency spectrum. Among them, the laser angle measurement technology has the advantages of long distance, high precision and strong anti-interference ability. Laser angle measurement uses a laser target indicator to aim at the target to emit a laser beam, and the laser lens receives the diffusely reflected laser light from the target to the four-quadrant detector to obtain target angle information. [0003] Among the existing satellite products, involving various high-precision rotating mechanism products such as pointing mechanisms, the calibration of the rotating shaft plays a very important role in the de...
