摘要： High-accuracy measurement of aberration refraction of the eye is needed in optometry for advanced investigation of vision and in refraction surgery for high quality laser-based operations of vision correction. Device contains a probing channel, (1) a measuring channel (2) and a channel of positioning, (3) orientation and providing an accommodation state of the eye. The probing channel is being composed of a laser, (6) two one-coordinate deflectors, (7) and (8) selector the first order of diffraction and collimating lens, which are arranged in series. The exit pupil of selector is coincided with front focus of collimating lens. Transferring telescope of the equivalent center of rays deflection by the first deflector in the equivalent center of rays deflection by the second deflector is placed between acousto-optic crystals of singlecoordinate deflectors. The entrance pupil of transferring telescope and the entrance pupil of selector of the first order of diffraction coincide with equivalent center of beams deflection by acousto-optic crystals of the second deflector. Measuring channel includes a objective lens, position-sensitive photo detector, which is placed in its focal plane, whose output is linked to a unit for information processing and display on the basis of a computer.(22).

The probing channel is being composed of a laser, two one-coordinate deflectors, selector the first order of diffraction and collimating lens, which are arranged in series. The exit pupil of selector is coincided with front focus of collimating lens. Transferring telescope of the equivalent center of rays deflection by the first deflector in the equivalent center of rays deflection by the second deflector is placed between acousto-optic crystals of singlecoordinate deflectors. The entrance pupil of transferring telescope and the entrance pupil of selector of the first order of diffraction coincide with equivalent center of beams deflection by acousto-optic crystals of the second deflector. Measuring channel includes a objective lens, position-sensitive photo detector, which is placed in its focal plane, whose output is linked to a unit for information processing and display on the basis of a computer. In addition, aperture diaphragm, placed in the point of foci coincidence of entrance and exit lenses, which may be made up in the form of a slot, whose longer side is oriented along the direction of beams deflection by the first deflector, is added in transferring telescope, which consists of spherical or cylindrical lenses. Light catchers, for example in form of light absorbing coating, which impinge at right angle, are placed around both aperture diaphragms outside the zone of first order of diffraction of both directions of light beams deflection.
