Abstract:
    This invention relates to one micro angle measurement method and device based on laser self mixture and intervene, which comprises the following steps: sending the laser beam output by laser into reflection lens of object surface and the incidence line goes off object angle rotation center and the laser output power uses one photoelectricity detector and when the object changes by micro angle, the detector detects laser output power; the angle change leads feedback light process each length and the output laser power changes one ripe circuit and through pre-set angle and output power relationship to realize object rotation angle.
