Abstract
A wavefront sensor for measuring a wavefront that includes an aperture mask configured to receive incident light, the aperture mask comprising a plurality of apertures irregularly spaced and arranged in a plurality of sub-windows that respectively transmit sub-beams of the incident light. A diffuser can receive the sub-beams transmitted by the plurality of apertures. A controller of the sensor is configured to identify measured sub-beams by convolving the sub-beams imaged on the diffuser with a map of the plurality of apertures; and measure the wavefront of the incident light based on changes in position of the sub-beams in a digital image of the diffuser relative to both reference positions and neighboring sub-beams.
