PROBLEM TO BE SOLVED: To obtain a reliable tomographic image and optical surface profile even if a position of an optical member is displaced in a spectral optical system.SOLUTION: A device has: an interference optical system in which a part of a low-coherent light is used as a measuring light, a part of the low-coherent light is used as a reference light, and reflected lights from the reference light and the measuring light are synthesized for interference the spectral optical system in which an interference light obtained by the interference optical system is dispersed into each frequency component, and a light receiving means receives the dispersed interference light and an adjustment means which adjusts relative positional relationship between the light receiving means and optical members other than the light receiving means installed on the spectral optical system on the basis of light reception signals out-put from the light receiving means in an ophthalmologic device obtaining image information of a subjected eye based on the light reception signals from the light receiving means.
