    • 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).

    • A head-mounted image display apparatus which is capable of selectively displaying images of normal and wide sizes efficiently by utilizing approximately all the pixels of a display device without the need of removing an optical system and which provides a bright image at high resolution and is easy to handle. The head-mounted image display apparatus has an image display device (2) for displaying an image, and a projection optical system for projecting the image displayed on the image display device (2) onto an observer's eye. The projection optical system includes an anamorphic optical system which is composed of an anamorphic lens (3) and a cylindrical lens (4), for example. The anamorphic optical system is rotatable about the optical axis. Accordingly, it is possible to selectively observe two images of the normal and wide sizes by rotating the anamorphic optical system about the optical axis through 90.degree. in either direction.
