technical field [0001] The invention relates to the field of optical measurement, in particular to an angle calibration device and a calibration method based on a constant temperature environment. Background technique [0002] Laser has the advantages of high brightness, good directionality, good monochromaticity, and good coherence, so it is widely used in various fields such as industry, agriculture, precision measurement and detection, communication and information processing, medical treatment, and military affairs. People can use lasers to process materials and carry out fine processing in disease treatment. [0003] With the development of social science and economy, the requirements for laser performance are getting higher and higher. If the laser can be operated finely, the target can be operated more specifically in practical applications. At present, the direction of the laser can be adjusted by changing the angle of the emission direction. However, this adjustmen...

Problems solved by technology

At present, the direction of the laser can be adjusted by changing the angle of the emission direction. However, this adjustment method mostly depends on the hardware and precision of the laser itself. The operation of the laser direction is also limited to changing the emission angle of the beam after the laser itself is adjusted. , there is no calibration specifically for the actual emission angle of the beam, and it reacts to the calibration of the laser itself, so the calibration accuracy is low
