Abstract: An electro-optical device includes an electro-optic crystal, a first electrode, and a second electrode. A voltage is applied to the electro-optic crystal by the first electrode and the second electrode. The electro-optic crystal has an incident surface and an emitting surface parallel to each other and deflects incident light made incident on the incident surface at an acute incident angle in an electric field direction in which a voltage is applied. A rotation axis of an incident angle is parallel to the electric field direction.

Abstract: A first structure in which connection strength between an air impermeable layer and a compressed fiber layer is relatively low and a second structure in which connection strength between the air impermeable layer and the compressed fiber layer is higher than the connection strength of the first structure. A vehicular compartment soundproofing structure includes the second structure that has good soundproofing performance in a high frequency band (1000 Hz or higher) and the first structure that has improved soundproofing performance in a middle frequency band with suppressing lowering of insertion loss in the middle frequency band (200 Hz to 630 Hz). Accordingly, the soundproofing performance of a whole vehicular compartment can be improved.

Abstract: An angle measurement device according to the present invention relates to an angle measurement device for measuring an incident angle of an incident light ray, and includes: at least one light deflector; a driving power supply; a light receiver; and a calculation unit. The light deflector is of a transmission type, has an electro-optic effect, and is configured to change an optical path of the light ray by a voltage applied from the driving power supply, and cause the light ray to enter the light receiver. The calculation unit is configured to calculate the incident angle based on the voltage at which an intensity of the light ray detected by the light receiver is maximum.

Abstract: An optical deflection apparatus is provided with an optical deflection element and a compensating optical element. The optical deflection element deflects incident light in a first direction (a voltage application direction) in which a voltage is applied (one-dimensional scan). The compensating optical element is an element which has an incidence surface and an emission surface, which compensates for a deflection deviation in a second direction that is perpendicular to the first direction and to an optical axis of the incident light of deflected light having been deflected by the optical deflection element and incident from the incidence surface, and which arranges a direction of travel of compensated light to be emitted from the emission surface on a same plane.
