Abstract
A wavefront sensor for measuring a wavefront contains an array of lenslets, a detector array, and a mask having a temporally fixed pattern containing one or more opaque regions that are substantially opaque to light from the wavefront. The mask comprises one or more transmissive regions that are transmissive of light from the wavefront. The mask and the array of lenslets are disposed such that light from the wavefront that is transmitted by the transmissive regions is focused by onto the detector array by the array of lenslets. The mask is adapted to be selectably disposed to any one of a plurality of predetermined positions, wherein a different group of lenslets from the array focuses light from the wavefront onto the detector array depending on which of the plurality of predetermined positions is selected.
