Filed: 1985-09-26
Abstract: PURPOSE:To increase the angular resolution of an encoder by providing plural pits at nearly the same radial positions of a rotary disk in a peripheral direction, and detecting the quantity of reflected light from a disk and obtaining information on a position in a rotational direction. CONSTITUTION:Light from a light source 3 is converged on the specific radial position of the rotary disk 1 through a path as shown by an arrow (a). Its reflected light reaches a photodiode 9 through a detection part 8 as shown by an arrow (b). The disk 1, on the other hand, is provided with pits 2 at nearly the same radial positions which are at equal intervals in the peripheral direction. Then, the quantity of reflected light from a pit 2 is detected to obtain rotational position information having the same period as the period of the pits 2 from the diode 9. Then, the resolution is determined by the formation precision of the pits 2 and the detection accuracy of an optical system, so those are improved to increase the angular resolution of the encoder.

Title: Temperature measuring apparatus
Inventor: WATANABE IKUO
IPC: G01K5/52
Filed: 1988-08-29
Abstract: PURPOSE:To perform accurate measurement even in a high electric field and in a high magnetic field, by inputting linearly polarized light into a photoelastic effect element, and detecting the phase difference between the polarized wave component in the direction of the maximum stress and the polarized wave component in the direction perpendicular to the maximum stress direction in the light through the element. CONSTITUTION:When an ambient temperature of a place, where a temperature-stress transducer 12 is provided, is increased, the stress of a part of a photoelastic effect element 14, which is located between embedded members 18 and 20, becomes larger in the direction of an axis (x) than the stress in the direction of an axis (y). Anisotropy is yielded in a refractive index of the element 14 owing to the stress. Meanwhile, light having specified intensity from a light source 32 is sent into a sensor part 10 through optical fiber 28. The light is converted into a parallel beam through a lens 26 and inputted into a polarizer 24. The polarizer 24 outputs linearly polarized light having the polarized wave component of 45 deg. with respect to the axis (x). The light is transmitted along an axis (z) in the element 14 and outputted to the opposite side. A phase difference phi is yielded between the polarized wave components Ex and Ey of the light in the axes (x) and (y). Since the phase difference phi is changed with the ambient temperature, the ambient temperature can be measured when the relation between the ambient temperature and the phase difference phi is obtained beforehand.
