摘要：PROBLEM TO BE SOLVED: To provide a method and a device for measuring the refractive characteristic of a human eye and precompensating it using adaptive optical elements. SOLUTION: A system 10 for precompensating the refractive characteristic of an eye includes optical components 16, 26, 28 for directing optical beams to the eye 12 in order to obtain reflection from the retina of the eye 12. reflected beams including refractive aberration caused by the eye 12 are separated into a plurality of individual beams by a small lens array 50. These individual beams are analyzed by a computer 2 to prepare a sensitivity map of the eye 12. The map is reversed by the computer 22 to form its negative, and a reflective surface 71 of an active mirror 6 is electronically constituted according to the negative map. Incident light from a stimulus being reflected by the active mirror 6 is therefore visible as undistorted light beams to the eye since aberration is compensated.
