CORRESPONDENCE RELATION SPECIFYING METHOD FOR ADAPTIVE OPTICS SYSTEM, WAVEFRONT DISTORTION COMPENSATION METHOD, ADAPTIVE OPTICS SYSTEM, AND STORAGE MEDIUM STORING PROGRAM FOR ADAPTIVE OPTICS SYSTEM

摘要

An adaptive optics system includes a spatial light modulator configured to spatially modulate a phase of an optical image incident on a modulation surface including N two-dimensionally arranged regions and a wavefront sensor including a lens array having N two-dimensionally arranged lenses corresponding to the N regions and an optical detection element for detecting a light intensity distribution including K converging spots formed by the lens array and configured to receive the optical image after the modulation from the spatial light modulator, wherein a correspondence relation between the region of the spatial light modulator and the converging spot formed in the wavefront sensor is specified.

1: A correspondence relation specifying method for an adaptive optics system, which includes a spatial light modulator configured to spatially modulate a phase of an optical image incident on a modulation surface including N (N is a natural number) two-dimensionally arranged regions and a wavefront sensor including a lens array having N two-dimensionally arranged lenses corresponding to the N regions and an optical detection element for detecting a light intensity distribution including K (K is a natural number and K≦N) converging spots formed by the lens array and configured to receive the optical image after the modulation from the spatial light modulator, wherein a correspondence relation between the region of the spatial light modulator and the converging spot formed in the wavefront sensor is specified, the correspondence relation specifying method comprising:
acquiring the light intensity distribution through the optical detection element in a state in which at least one region of the N regions of the spatial light modulator is set as a target region, a phase pattern having linearity in at least one direction is displayed in the target region, and a spatially non-linear phase pattern is displayed in a plurality of regions surrounding the target region.
