FIELD: medicine.
SUBSTANCE: ophthalmic wave front sensor comprises: light source; first light-guiding element; first optical wave front relay system; matrix of two-dimensional position recording devices; and matrix of extraction partial wave front elements located before two-dimensional matrix of position registration devices. Each two-dimensional position recording device is configured to detect value of two-dimensional image spot centroid deviation from reference position and output measuring signal indicating value of two-dimensional deviation. Each element of selection in matrix elements of partial selection of wave front is made with possibility of partial selection of wave front of relay of wave front and focusing of selected partial wave front on corresponding two-dimensional device for recording position in matrix of two-dimensional position registration devices. At that, sampling elements partial wave front physically spaced apart so that each selected partial wave front of wave front, reflected from eye, is focused only on corresponding two-dimensional device for recording position corresponding to element of selection of partial wave front. Another version of ophthalmic wave front sensor package assumes scanner/deflector beam arranged along beam path, made with possibility of full capture and scanning beam relay wave front.
EFFECT: using given group of inventions will allow to continuously measure refraction eye conditions.
