Spot diameter (Optical displacement sensor) - Glossary - Displacement Sensors

Spot diameter (Optical displacement sensor)

The spot diameter is generally defined to be 1/e2(13.5 %) of the sensor's laser beam center light strength. There is light that leaks outside the defined range; therefore, if the reflective rate of the light is high compared to the area around the sensing point, influences may be exerted.
