A：
In high temperature or highly reflective surface environments, laser displacement and ranging sensors may have measurement errors. Common coping methods include:
1. Choose a laser with the right wavelength: Using laser wavelengths that are more sensitive to high reflectivity or special materials (such as blue or green light) can improve measurement stability.
2. Add filtering and temperature compensation functions: Equip filters to reduce the impact of background interference light, and enable temperature compensation algorithms to ensure accurate measurement when the temperature changes.
3. Use multi-point averaging or dynamic correction algorithms: Improve measurement stability by averaging multiple measurement points or dynamically correcting reflective changes.
4. Surface treatment: Apply matte tape or spray matting agent on reflective surfaces to improve laser reflection characteristics.
5. Choose anti-interference models: Use industrial-grade sensor products with strong anti-reflective capabilities and thermal stability design.
These methods can effectively improve the reliability and accuracy of laser displacement and ranging in extreme environments.
