Paper Abstract

The symmetric two beams are first used to irradiate a single laser angle sensor overlapping and the reflected films are plated on the reflecting plane of LAS. It breaks through the limitation of the measured angle area limited by the full internal-reflection angles. This method makes the measured angle area to be increased to 140 degrees in the static state and 76 degrees in the dynamic state, the experimental errors of angle measurement are reduced to 0.007 degrees. The output of measured angles is displayed as numbers and printed by a computer.
