Claim:
1. An adjustment 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 and a wavefront sensor including a lens array having a plurality of two-dimensionally arranged lenses and an optical detection element for detecting a light intensity distribution including converging spots formed by the lens array and configured to receive the optical image after the modulation from the spatial light modulator and which compensates for wavefront distortion by controlling a phase pattern displayed in the spatial light modulator based on a wavefront shape of the optical image obtained from the light intensity distribution, wherein the correspondence relation between the modulation surface and the wavefront sensor is adjusted, the adjustment method comprising: a first light intensity distribution acquiring step of acquiring the light intensity distribution through the optical detection element in a state in which one of a first phase pattern having linearity in at least one direction and a spatially non-linear second phase pattern is displayed in a first region on the modulation surface for corresponding to one of the plurality of lenses or two or more lenses adjacent to each other and the other of the first and second phase patterns is displayed in a second region surrounding the first region; and an adjusting step of adjusting the correspondence relation between the modulation surface and the wavefront sensor based on clarity of the converging spot included in the light intensity distribution obtained in the first light intensity distribution acquiring step.
