Embodiment Construction
[0033] like figure 1 As shown, in the actual operation of the system, there are four processes at the same time, the main optical path transmission process, the data acquisition imaging process, the adaptive optics correction process and the subject-related process. Including a semiconductor laser light source 1, a plurality of reflective beam reduction beam expansion systems 11-18, a two-dimensional scanning galvanometer composed of an X-direction scanning galvanometer 23 and a Y-direction scanning galvanometer 24, a Hartmann wavefront sensor 9, deformation The mirror 22, the collection lens 27, the pinhole 4 and the photomultiplier tube 5, the photodetection system, the data acquisition and processing system 6, and the other eye visual target system 30. The collimating mirror 21 , the deforming mirror 22 , the X-direction scanning galvanometer 23 , the Y-direction scanning galvanometer 24 , the optometry lens 25 and the Hartmann front conjugate plane 26 are in conjugate posi...
