    摘要： An optical imaging apparatus includes an optical probe and an apparatus main body which controls and drives the optical probe via a connecting cable. The optical probe includes a low-coherence light source, a half mirror, an XY reflecting mirror scan, an objective optical system, a reflecting mirror, a modulating mirror, and a photo detector. In the optical probe, the modulating mirror and the objective optical system, as optical path length interlockingly adjusting elements, are integrally arranged to an optical path length interlockingly adjusting base, together with a reflecting-side lens. The optical probe has an advancing and regressing driving unit which advances and regresses the optical path length interlockingly adjusting base in the optical axis direction (Z direction).

    摘要： A dispersion element includes a prism having a first transmission surface and an oppositely disposed second transmission surface, and an optical element having a third transmission surface and an oppositely disposed diffraction optical surface on which a diffraction grating is arranged. The prism and the optical element are integrated into one body by cementing the first transmission surface to the third transmission surface. The third transmission surface and the diffraction optical surface are non-parallel to each other in a plane perpendicular to grooves of the diffraction grating.
