TANGENTIAL PHASE FRONT SENSOR Russian patent published in 2009 - IPC G02B26/06 

FIELD: instrument engineering.

SUBSTANCE: invention concerns optical instrument engineering, particularly adaptive optics, and can be used in construction of adaptive optical systems. The specified technical effect is ensured by that it is supplemented with 16N scale amplifiers of a summator, 40 scale group amplifiers, whereas N two-areal photodetectors are arranged in aperture points on the concentric circles. The interface of each two-areal photodetector is matched with the radius of a relevant circle.

EFFECT: invention aims at enhancement of the phase front sensor that is ensured by possibility to measure phase front parametres as an expansion in coefficients in Zernike basis.
