Patent ID: 8899751

Claim:
An ophthalmic photographing apparatus for obtaining a tomographic image of a fundus of an examinee's eye by optical coherence tomography (OCT) using low coherent light, the apparatus comprising: an OCT optical system configured to obtain the tomographic image of the fundus including: an OCT light source; a splitter for splitting light emitted from the OCT light source into measurement light guided to a measurement optical path and reference light guided to a reference optical path; an optical scanner arranged in the measurement light path for scanning the light from the OCT light source on the fundus of the examinee's eye; and a photodetector for detecting light generated by synthesis of the measurement light reflected from the fundus and the reference light; and a calculation control unit configured: to obtain an OCT front image as a moving image with the use of the OCT optical system by two-dimensionally scanning the light from the OCT light source with the optical scanner and by detecting the light generated by synthesis of the measurement light and the reference light with the photodetector such that the OCT front image is generated based on an output signal from the photodetector, the OCT front image being a front image of the fundus; to display the OCT front image as the moving image obtained with the use of the OCT optical system on a monitor; to set a line on the OCT front image as the moving image such that the tomographic image of the fundus is obtained based on the line; and to obtain the tomographic image of the fundus corresponding to the line with the use of the OCT optical system by scanning light from the OCT light source with the optical scanner based on a scanning position corresponding to the set line and by detecting the light generated by synthesis of the measurement light and the reference light with the photodetector.
