Abstract

We demonstrate the performance of an optical differentiation wavefront sensor (ODWS) relying on an optical system that images the pupil to a camera. A binary pixelated transmission filter with a linear amplitude-transmission gradient is located in a far field of the pupil. The ODWS uses the fluence data measured in the detection plane for two orthogonal orientations of the filter to determine wavefront-slope data along the two corresponding directions in the pupil plane. This technique allows for acquisition in real-time without moving parts, providing high resolution, high dynamic range, and achromatic wavefront sensing for astronomical imaging or metrology applications.
