  • Patent number: 7411675
    Abstract: A linearly polarized light output unit (701) outputs a linearly polarized light. A first phase modulation unit (703) includes a first polarization axis and modulates a phase of the linearly polarized light. A second phase modulation unit (704) includes a second polarization axis orthogonal to the first polarization axis and modulates the phase of the linearly polarized light. A signal supply unit (705) supplies a modulation signal (vb) for modulating the phase of the linearly polarized light to one of the phase modulation units. A light intensity detection unit (707) detects an intensity of a light emitted from a phase modulation unit (702), to which the signal is supplied, to a sample (106) that contains an optically active material by causing a polarization plane of the light to be rotated and the light to be transmitted by the sample (106). An optical rotation angle calculation unit (708) calculates an optical rotation angle based on the modulation signal (Vb) and the detected light intensity.

  • Patent number: 7015778
    Abstract: The actuator device includes a rotation body and a rotation restriction plate. The rotation axis of the rotation body is placed on the rotation axis holding member. The rotation restriction plate is placed on the side opposite the rotation axis holding member with respect to the rotation axis of the rotation body. As a result, when the drive means is operated to move the rotation body thereby causing the abutment of the rotation body and the rotation restriction plate, the rotation axis of the rotation body is always subjected to a force which presses it against the rotation axis holding member, and there is no force which urges the rotation body to be floated up from the rotation axis holding member.
