| description | The invention discloses a large dynamic angle measuring device for a non-contact scanning reflector. The large dynamic angle measuring device comprises a laser transmitting module, a spatial filter, a receiving screen, a distributed detection system and a main control computer, the laser emission module generates a circular light spot as a measurement target, the circular light spot enters the measured scanning reflector after being shaped by the spatial filter, and the laser light spot is received on the receiving screen after being reflected by the measured scanning reflector; the distributed detection system detects and analyzes the laser spots on the receiving screen, caches the collected data and uploads the data to the main control computer; and when the detected scanning reflector moves, the position of the light spot image on the receiving screen is changed, so that the deflection angle of the detected scanning reflector is calculated. According to the invention, absolute measurement of a large dynami |
