Review of holographic wavefront sensors

Measurement of the wave front is an actual problem for optics, astronomy, and ophthalmology. The wave front of any complexity can be represented in the form of Zernike polynomials. Measurement of the wave front can be done with the help of different devices: the classic Hartmann sensor, the Shack-Hartmann sensor and others. Recently, the direction of holographic sensors has been actively developing. They allow to make measurements in a dynamic mode. Holographic sensors are characterized by cross modulation noises, which arise from the construction of sensors based on the multiplex. The report will consider existing wave front sensors, including holographic.
