Wavefront curvature sensorIt is an optical detection device used for precise measurement of the phase distribution and curvature changes of light waves. Its core function is to convert the "phase information" of light into a quantifiable "intensity signal", thereby analyzing the wavefront distortion during the propagation of light beams. It is widely used in fields such as adaptive optics, laser technology, astronomical observation, biomedical imaging, etc. It is one of the key devices for achieving "beam quality control" and "high-resolution imaging".
Wavefront curvature sensorBased on the mathematical relationship between wavefront curvature and phase distribution, the wavefront phase information can be directly derived by measuring the curvature changes at different positions in the light field.
Precautions for use:
1. Environmental control:
Avoid vibration: This device is sensitive to mechanical vibrations (especially dual detector types) and should be placed on an isolation platform;
Temperature/humidity stability: Changes in environmental temperature and humidity can cause thermal expansion, contraction, or condensation of optical components. It is recommended to use in a clean environment with a temperature of 20-25 ℃ and a humidity of 40% -60%.
2. Optical calibration:
Regular calibration: Use a "standard spherical wave light source" to calibrate the detector position and light intensity response, avoiding accuracy drift after long-term use;
Avoid stray light: During measurement, it is necessary to block ambient stray light (such as using a light shield) to prevent interference with the collection of light intensity distribution.
3. Maintenance and upkeep:
Optical lens cleaning: If there is dust on the surface of the lens, use specialized optical wiping paper dipped in anhydrous ethanol to gently wipe it, and do not touch it directly with your hands;
Detector protection: Avoid direct exposure of strong light to the detector (which may cause pixel damage). When idle, turn off the light source and cover the lens cover.
