Information Regarding Terminology, Laser Safety And More

Optical distance measurement sensors are used in a wide variety of industrial, commercial, and research applications. Most sensors use a visible or infrared laser beams to project a spot of light onto a target, the surface to which the distance is to be measured. The distance from the spot back to the light-detecting portion of the sensor is then measured in one of several ways. Acuity employs laser triangulation and modified time-of-flight principles in its laser measurement sensors.

There are many factors to consider when specifying a laser distance sensor. They include maximum range, sensitivity, target reflectance and specularity, accuracy and resolution, environmental conditions, and sample rate. Please view our common laser terms glossary to learn more.
