WIDTH MEASUREMENT USING LASER SCAN MICROMETER

Laser-scan-micrometer consist of emitter and receiver. LAP METIS sensors use a light plane generated by a laser beam, which is deflected by a rotating prism and directed by a lens. 

In the receiver, the laser is focused on a diode. For each pass, the laser needs a fixed time interval.

 If there is an object in the laser plane, the receiver is shadowed for a certain amount of time. This time is proportional to the dimension of the object.
