LASERS and Photodiode Pixel Arrays combine to form advanced measurement systems for position and relative angles, at the speed of light.  The Techmor LA-1 uses these advanced sensors to define the two angles of the LASER plane (Steering and Camber).  High-speed electronics can resolve millions of pixels per second, and nanosecond triggers accurately determine the LASER line position.
