Many areas of optical science and technology require fast and accurate measurement of the radiation wavefront shape.
Today there are known a lot of wavefront sensor (WFS) techniques, and their number is growing up. The last years have
brought a growing interest in several schematics of WFS, employing the holography principles and holographic optical
elements (HOE). Some of these devices are just the improved versions of the standard and most popular Shack-Hartman
WFS, while other are based on the intrinsic features of HOE. A holographic mode wavefront sensor is proposed, which
makes it possible to measure up to several tens of wavefront modes. The increase in the number of measured modes is
implemented using the conversion of a light wave entering the sensor into a wide diffuse light beam, which allows one to
record a large number of holograms, each intended for measuring one of the modes.
