Wavefront Measuring Method for Adaptive Optics System

A non-transitory computer readable medium encoded with instructions for controlling an optical-image pickup apparatus configured to radiate measurement light onto a subject, to measure a wavefront aberration generated at the subject with a wavefront measurement device, to correct the aberration with a wavefront correction device, and to acquire an optical image of the subject, the method comprising:

• receiving a first set of quality data that is representative of a quality of wavefront data, wherein the wavefront data is an estimation of wavefront aberrations generated at the subject;
• comparing the first set of quality data to a first threshold;
• in a first case wherein the comparison of the first set of quality information indicates that the wavefront data is of sufficient quality then performing normal adaptive optics feedback comprising:
• sending a first set of control information to the optical-image pickup apparatus instructing the optical-image pickup apparatus to compensate for aberrations based on an estimated shape of the wavefront based on the received wavefront data;
• and
• re-estimating the shape of the wavefront based on re-acquired wavefront data and sending a new first set of control information to the optical-image pickup apparatus instructing the optical-image pickup apparatus to compensate for aberrations based on the re-estimated shape of the wavefront;
• and
• in a second case wherein the comparison of the first set of quality information indicates that the wavefront data is not of sufficient quality then performing an initial adjustment comprising:
• sending a second set of control information to the optical-image pickup apparatus instructing the optical-image pickup apparatus to modify the optical path in which measurement light is radiated onto the subject;
• receiving a new first set of quality data that is based on new wavefront data after the optical path has been modified;
• and
• re-comparing the new first set of quality data to the first threshold;
• in a third case wherein the comparison of the first set of quality information indicates that the wavefront data is of sufficient quality then performing the normal adaptive optics feedback in which the optical path has been adjusted based on the second set of control information;
• and
• in a fourth case wherein the comparison of the first set of quality information indicates that the wavefront data is not of sufficient quality then re-performing the initial adjustment based on a new second set of control information.
