Principle Principle




The laser beam is emitted from a semiconductor laser, reflected by a multi-faceted mirror and a plane mirror, and then passes through a collimating F(θ) lens to scan the measured object in parallel alignment. The shadow of the beam formed by the measured object is focused through the receiver lens and converted into an electronic signal. The size of the measured object is calculated based on the time taken for the beam to be blocked and form a shadow.
