Abstract
An OCT apparatus includes an OCT optical system that splits light from an OCT light source into a measurement optical path and a reference optical path and detects a spectral interference signal between measurement light and reference light, an image processor that processes the spectral interference signal to acquire OCT data of an examinee's eye, an optical scanner that deflects the measurement light and performs scanning on tissue of the examinee's eye, and a light guiding optical system that includes an objective optical system curving a concentrating plane such that the concentrating plane has a convex shape toward a side of a fundus, and forms the concentrating plane of the measurement light in an anterior chamber.
Claims15
An OCT apparatus comprising:
- an OCT optical system that causes an optical splitter to split light from an OCT light source into a measurement optical path and a reference optical path, and detects a spectral interference signal between measurement light guided to an examinee's eye through the measurement optical path and reference light from the reference optical path;
- an image processor that processes the spectral interference signal output from the OCT optical system to acquire OCT data of the examinee's eye;
- an optical scanner that deflects the measurement light from the optical splitter, and performs scanning on tissue of the examinee's eye;
- and
- a light guiding optical system that includes an objective optical system, guides the measurement light from the optical splitter to the examinee's eye through the objective optical system, and forms a concentrating plane of the measurement light in an anterior chamber of the examinee's eye,
- wherein the objective optical system curves the concentrating plane such that the concentrating plane has a convex shape toward a side of a fundus of the examinee's eye.
