Binocular wave front aberration vision optical analysis system

Abstract

The invention relates to a binocular wave front aberration vision optical analysis system, relates to the technical field of medical optics, and is used for achieving the technical effect of correcting binocular aberration. The system comprises a laser light source, a right eye subsystem and a left eye subsystem, wherein the right eye subsystem forms one right eye reference light path and one right eye measurement and correction light path through a right first spectroscope, a right dispersion prism, a right flat mirror, a right anamorphoscope, a right second spectroscope, a right Hartmann-Shack sensor, a right eye vision object, a right reflection unit, a right beam expanding unit, and a right beam shrinking unit; the left eye subsystem forms one left eye reference light path and one left eye measurement and correction light path through a left first spectroscope, a left dispersion prism, a left flat mirror, a left anamorphoscope, a left second spectroscope, a left Hartmann-Shack sensor, a left eye vision object, a left reflection unit, a left beam expanding unit, and a left beam shrinking unit. By adopting the system, the measurement and correction of binocular aberration can be realized.

Description

technical field [0001] The invention relates to medical optical technology, in particular to a technology of a binocular wavefront aberration vision optical analysis system. Background technique [0002] Humans usually use binocular vision, and the visual acuity and contrast sensitivity of binocular vision are about 1.1 times and 1.4 times higher than those of monocular vision. However, the quality of binocular vision is not entirely determined by the neural factors of the visual system, but also depends on the difference in the optical imaging quality of the two eyes, the difference in higher-order aberrations between the two eyes, the difference in the shape of the cornea, the difference in this optical aberration Common after surgery. In general, as the difference in optical quality between the two eyes increases, the quality of binocular vision decreases. [0003] As an objective wavefront analyzer widely used at present, the main principle of the Hartmann Shack wavefr...

Problems solved by technology

However, the Hartmann Shack wavefront aberrometer can only measure the monocular wavefront aberration data, and does not involve the correction of binocular aberrations.
