Paper Abstract

The distance between the charge couple-device (CCD) and the micro lens array is one of assembling errors which affects the accuracy of Hartmann-Shack wavefront detector. The correction of this motion assembly parameter can effectively reduce the wavefront detector error. The relationship between the subaperture spot centroid shift amount, caused by the spherical wavefront passing through the micro lens, and the structural parameters of wavefront sensor was derived theoretically. By utilizing the relationship, defined an assembly parameter to guide the assembly process. Experiments verified the rationality of theoretical derivation then achieved a sample Hartmann-Shack wavefront sensor. This method can not only guide the Hartmann-Shack assembly quickly, but also improve the measurement accuracy of wavefront sensor.
