Embodiment Construction
[0029] The angle optical measuring device and angle measuring method of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0030] see figure 1 , the angle optical measuring device comprises two light sources 11 and 12 arranged along the optical axis of the angle optical measuring device, a dichroic prism 13, a half mirror 14, a photodetector 15, an image processor 16, a rough template installed test object ( figure 1 Only the rough template 17) and the first lens 18 installed on the measured object are shown;
[0031] The two light sources 11 and 12 are used to generate coherent light, and the light beams emitted by the two light sources 11 and 12 form a certain angle with each other; The prism 13 combines beams to generate coherent light;
[0032] The dichroic prism 13, the half-mirror 14 and the measured object are arranged in sequence; the coherent light generated by the dichroic prism 13 passes through the ha...
