The AR100 Laser Displacement Sensor is a the most compact triangulation sensor that measures distance by projecting a beam of laser light that creates a spot on a target surface. Reflected light from the surface is viewed from an angle by a CMOS detector array inside the AR100 sensor. The target’s distance is calculated from the image pixel data using the sensor’s microprocessor. The distance is transmitted through serial communications and analog outputs. A variety of models are specified, each to allow a different measurement range and standoff.
