Abstract

An optical tomographic image photographing apparatus includes: an OCT optical system for capturing tomographic images of an object to be examined, the OCT optical system including a light source, a splitter for splitting a light from the light source into a measurement optical path and a reference optical path, an optical scanner, and a detector for detecting a spectrum of light obtained by combining the light of the measurement optical path reflected from the object and the light from the reference optical path; a drive unit to move at least a part of optical components of the OCT optical system in an optical axial direction; a monitor to output at least the tomographic image; and a display controller for displaying the tomographic image and identifying information used to determine whether the tomographic image output to the monitor is a normal image or a reverse image.

First claim

The invention claimed is:

1. An optical tomographic image photographing apparatus, including:
an optical coherence tomography (OCT) optical system that captures tomographic images of an object to be examined, the OCT optical system including:
a light source;
a splitter that splits a light from the light source into a measurement optical path and a reference optical path;
an optical scanner, placed in the measurement optical path, that scans light on the object to be examined;…
