摘要： Laser light output from a laser light source is irradiated onto a transmission-type scale. Due to movement of the transmission-type scale, a polarization angle of transmitted light varies in accordance with variations in orientations of half-wave plates arrayed in a longitudinal direction. It is difficult for the polarization angle to be affected by noise factors such as external light or the like. Light intensity of a polarized light component, which is transmitted through an analyzer and detected at a photo-detector, varies in accordance with the polarization angle. Thus, the light intensity varies as the transmission-type scale moves, and a detection signal is output to a movement amount computing device. When an amount of movement is computed on the basis of the signal, the exact amount of movement can be detected.

摘要： Laser light emitted from a laser light source is irradiated onto a transmission-type scale, and is diffracted by a polarization hologram recorded on the transmission-type scale. Only polarization directions of ±1-order diffracted lights, among diffracted lights, are rotated by 90°. The ±1-order diffracted lights interfere with one another such that interference fringes are formed on a light-receiving surface of a photo-detector. Interference light of the ±1-order diffracted lights is transmitted through a polarizing plate. A portion of transmitted light is passed through respective slits of a slit plate and is irradiated onto the photo-detector, and intensity of irradiated light is detected. On the other hand, 0-order diffracted light, ±2-order diffracted lights, and the like, whose polarization directions are not rotated, cannot pass through the polarizing plate, and are blocked before being detected at the photo-detector.

摘要： An optical reproducing method. A diffracted light is generated by irradiating a reference light onto a hologram. A combined light is generated by applying a direct-current component formed by a polarized light having a third polarization component with a first polarization plane having a polarization direction orthogonal to the diffracted light and having the same phase as the diffracted light, and a fourth polarization component with a second polarization plane having an opposite phase to the diffracted light, onto the diffracted light. The combined light is separated into a fifth polarization component including a first polarization component and the third polarization component, and a sixth polarization component including a second polarization component and the fourth polarization component. A first reproduced image is reproduced from the separated fifth polarization component, and a second reproduced image is reproduced from the separated sixth polarization component.
