How do laser displacement and ranging deal with measurement errors on hot or reflective surface？

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.
