Relationship Between Measurement Range and Accuracy of Laser Displacement Sensors

Laser displacement sensors measure target displacement with laser beams and offer high accuracy, fast speed, and non-contact measurement. Measurement range and accuracy are two important performance indicators with a trade-off relationship.

Generally, a larger measurement range increases applicability but can reduce accuracy due to environmental factors such as air turbulence and temperature changes affecting the laser beam. Accuracy refers to the deviation between measured and true values and is influenced by sensor design, measurement principle, and signal processing.

Selecting a laser displacement sensor requires balancing range and accuracy per application needs. Improving performance can involve optimizing sensor design, enhancing beam optics and signal processing, and reducing environmental interference.
