Abstract: A flexible thin film is supported by a frame member through two end portions opposing each other. A reflection surface is provided on the flexible thin film to reflect light. A first electrode is provided integrally with the flexible thin film. A second electrode is substantially fixed to the frame member so as to oppose the first electrode on an opposite side of the reflection surface. A third electrode is substantially fixed to the frame member so as to oppose the first electrode on the same side as the reflection surface. An optical opening for introducing light into the reflection surface is provided on the side of the reflection surface. At least one of the second and third electrodes is divided in the direction connecting the two end portions. The configuration of the reflection surface is controlled to a desired configuration by applying a desired voltage selectively to between the first electrode and the divided second or third electrode.

Abstract: An optical element supporting device has one ends of two parallel plate springs, which are extended in a tangential direction, fixed to a holder, has the other ends thereof fixed to a fixture member, and has a collimator lens locked in an opening of the holder. A base fixed to the bottom of the fixture member has two yokes formed thereon. Magnets each polarized in two directions are fixed to the insides of the yokes. Coils are fixed to two surfaces of the holder opposed to the magnets. A target is fixed to the holder, and a sensor is fixed to the bottom of the base. When a current flows into the coils, electromagnetic force is produced along an optical axis due to the interaction between the coils and the magnets opposed to the coils. This causes the parallel plate springs to loosen. Consequently, the holder, target, collimator lens, and coils move as a whole along the optical axis.

Abstract: A surgical operation navigation apparatus comprises a medical image storage section that stores three-dimensional information of a subject measured by a medical image diagnosis unit. A modification information storage section modifies and stores the three-dimensional information of the subject based on predicted modification of the subject. A morphological shape measuring instrument measures a three-dimensional morphological shape of the subject. A morphological shape information storage section compares a three-dimensional morphological shape of a subject with three-dimensional information, and selects and outputs three-dimensional information of the subject that is the most analogous to the morphological shape of the subject. A data image generating section generates data image from the selected, outputted three-dimensional information of the subject.

Abstract: A laser microscope includes a beam scanning mechanism to scan a laser beam. An objective lens condenses the beam, and receives from a specimen the light by a linear and a non-linear phenomenon evoked by condensation of the beam, and a reflect light. A first beam splitter is arranged between the objective lens and the scanning mechanism, and separates the laser beam, the light by the linear phenomenon and the reflected light, from the light by the non-linear phenomenon. A first photodetector detects the light by the non-linear phenomenon. A second beam splitter is arranged between a light source and the scanning mechanism to separate the beam from the light by the linear phenomenon. A second photodetector detects the light passing a pinhole arranged at a position conjugative to the focal point of the objective lens among the light by the linear phenomenon and the reflected light.
