ABSTRACT:
An optical image measurement device comprises: an interference-light generator configured to generate an interference light by splitting a low-coherence light into a signal light and a reference light and superimposing the signal light having passed through an eye and the reference light having passed through a reference object; a detector configured to detect the generated interference light; a calculator configured to obtain intensity distribution of the interference light in the eye, based on a result of the detection by the detector; a determining part configured to determine a projection position of the signal light to the eye, based on the obtained intensity distribution; and an image forming part configured to form an image of the eye, based on a result of detection of a new interference light based on a new signal light projected toward the determined projection position and a new reference light having passed through the reference object.
