Title: Ophthalmologic apparatus
Inventor: HAYASHI TAKESHI
IPC: A61B3/10
Filed: 2018-01-12
Abstract: PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of measuring intraocular distances with high accuracy and without increasing size and complexity of the apparatus.SOLUTION: A photographing part of an ophthalmologic apparatus in an embodiment photographs an eye to be inspected from two or more different directions. An optical system splits light from a light source into measurement light and reference light and detects interference light of returned light of the measurement light from the eye and the reference light. A changing part changes optical path length of the measurement light (reference light). A controller controls the photographing part to perform first photography and the optical system to perform first detection when first optical path length is set and controls the photographing part to perform second photography and the optical system to perform second detection when second optical path length is set. A calculator calculates a displacement between the first and second images, calculates a difference between the first and second optical path lengths, and calculates the distance based on the displacement and the difference, when each of the first and second sites corresponds to a coherence gate.SELECTED DRAWING: Figure 9
