Abstract
Wavefront sensors are provided herein. An aperture mask is configured to receive incident light the wavefront of which is to be measured and comprising irregularly spaced apertures that respectively transmit sub-beams of the incident light. A diffuser is configured to receive the sub-beams transmitted by irregularly spaced apertures of the aperture mask. A camera, having a focal plane in which the diffuser substantially is located, is configured to obtain a digital image of the diffuser and thus to obtain a digital image of the incident light the sub-beams of which the aperture mask transmits onto the diffuser. A controller is configured to electronically receive the digital image of the diffuser and to measure the wavefront of the incident light based on the digital image. Methods also are provided.
