Abstract
An apparatus for estimating a wavefront parameter includes a light source, a lenslet array, a detector for detecting light generated by the light source and passed through the lenslet array, a wavefront corrective element disposed between the lenslet array and the light source; and a data analyzer configured to estimate at least one wavefront parameter at a plane located on the light source side of the corrective element. The lenslet array and the sensor array are arranged to form a wavefront sensor, and the wavefront corrective element is configured to correct an aberration of the wavefront.
