Patent ID: 7926947

Claim:
An ophthalmic examination system for examining an eye to be examined, in which an image containing an examination target is presented to said eye to be examined and the eye is examined based on how the eye sees the target; said ophthalmic examination system comprising: target light generating means generating an unpolarized target light beam for forming said target in said image; background light generating means generating an unpolarized background light beam for forming a background which is the region of said image excluding said target; and combining means for combining said target and background light beams and projecting the resultant light beam to said eye to be examined; wherein: said combining means has a boundary surface which receives incidence of said target and background light beams and divides each of said incident target and background light beams equally into transmitted and reflected light beams without changing the polarization state thereof; said target and background light beams are incident on said boundary surface at angles which are conjugate with each other; and either one of first and second resultant light beams is projected onto said eye to be examined, said first resultant light beam resulting from combining said target light beam as transmitted through said boundary surface and said background light beam as reflected from said boundary surface, said second resultant light beam resulting from combining said target light beam as reflected from said boundary surface and said background light beam as transmitted through said boundary surface.
