The AR600 laser displacement sensor models employ triangulation measurement principles with a CMOS detector array. This technique yields accurate distance measuring and unmatched sensitivity on targets with low reflectivity.

The AR600 optical measurement sensor projects a beam of visible laser light that creates a spot on the target surface. The reflected light from the surface is viewed from an angle by a CCD line scan camera and the target's distance is computed from the image pixel data. The size of the measurement triangle is a function of the sensor span and case length.

Thickness gaging is achieved by using two opposing sensors with laser spots aimed at opposite sides of a target. The sensor readings are subtracted from the sensor separation distance to yield a real-time thickness measurement. For the most accurate thickness measurements, the sensors should be synchronized using a single serial port to sample "on-command".
