摘要：
A method of determining a reference calibration setting for an adaptive optics system comprising a detecting device for detecting light from an object； and at least one controllable wavefront modifying device arranged such that light from the object passes via the wavefront modifying device to the detecting device. The method comprises: arranging a light-source between the object and the wavefront modifying device to provide a reference light beam to the detecting device； for each of a plurality of orthogonal wavefront modes: controlling the wavefront modifying device to vary a magnitude of the orthogonal wavefront mode； acquiring a series of readings of the detecting device, each reading corresponding to one of the magnitude； determining a quality metric value for each reading, resulting in a series of quality metric values； and determining a reference parameter set for the wavefront modifying device corresponding to an optimum quality metric value.
