Abstract
A confocal microscope apparatus capable of rapidly obtaining a tomographic image using OCT measuring. The confocal microscope apparatus for obtaining a tomographic image of a measuring object includes a light modulating section that modulates the frequency of the reference light. The light modulating section includes: a diffraction grating element for dispersing the reference light; a collimator lens for collimating the reference light dispersed by the diffraction grating element; and a reflection mirror for reflecting the reference light transmitted through the collimator lens back to the collimator lens and inputting to the diffraction grating element. The reflection mirror is pivoted on a position which is offset from the optical axis of the collimator lens.
