VISIUAL SENSE EXAMINATION DEVICE

A visual sense examination device includes: a beam source 11 that emits a visible laser beam 50a and an infrared laser beam 50b; an image projection optical system 14 that includes a scanning unit 20 oscillating at a first frequency to two-dimensionally scan the visible laser beam 50a, and that emits the visible laser beam 50a to a retina 74 of a subject to project an image on the retina 74 of the subject; an infrared beam optical system 15 that includes a scanning unit 22 oscillating at a second frequency different from the first frequency, to two-dimensionally scan the infrared laser beam 50b, and that emits the infrared laser beam 50b to the retina 74 of the subject; a detector 40 that detects the infrared laser beam 50b reflected by the retina 74 of the subject; and a control unit 30 that controls the emission of the visible laser beam 50a and the infrared laser beam 50b from the beam source 11, and detects a state of a fundus of the subject from an output signal of the detector 40.
