Abstract:
1. An optical image measuring device comprising: a light source configured to output low-coherence light; an optical coupler configured to generate the interference light by separating the low-coherence light into a signal light and a reference light and superimposing the signal light via the object to be measured on said reference light; an optical fiber configured to guide said interference light; a dispersion part configured to spectrally decompose said guided interference light; a detector configured to receive said spectrally decomposed interference light, an image forming part configured to form an image of the object to be measured by analyzing said interference light received by said detector; a specifying part configured to specify an amount of the interference light received on a light-receiving surface of said detector; and a drive mechanism configured to alter the relative position or orientation between said light-receiving surface and the exit end of said optical fiber, to the relative position or orientation when the amount of the received interference light reaches a substantial peak.
