- 摘要：
PROBLEM TO BE SOLVED: To provide an ophthalmologic photographing apparatus, restraining deterioration of image quality of a photographed image due to displacement of interference light on a light receiving surface of a light receiving element, achieving sensitivity adjustment at a level which could not be solved in the conventional adjusting mechanism, and obtaining preferable and high-reliability tomographic image and optical surface profile.
SOLUTION: The ophthalmologic photographing apparatus includes: a light guide means for guiding a light beam for calibration to a spectral optical system an optical member for causing interference of the light beam for calibration an adjusting means for adjusting the relative positional relationship between the outgoing position of the light beam for calibration from the light guide means and a light receiving means based on the spectral information obtained by causing a light receiving means to receive the light beam for calibration and an operation means for computing correction information for correcting the distribution state of the respective wavelength components to the respective pixels of the light receiving means based on the spectral information of the light beam for calibration subjected to interference obtained by the receiving means after the relative positional relationship is adjusted by the adjusting means.
