摘要： A detecting unit provided with an optical system is disposed away from a control unit formed by an electric circuit and an optical transmission/receiving means, and the detecting unit and the control unit are coupled through a transmission optical fiber. The control unit transmits to the detecting unit through the optical fiber a light wave which was subjected to the intensity modulation by a sinusoidal wave of a predetermined frequency. The transmitted light wave is branched into at least two branched optical paths within the detecting unit thereby to perform the phase modulation as to the respective light waves. The light waves passed through the respective branched optical paths are subjected to the phase modulation by the sinusoidal waves which differ in phase 1/4 period by 1/4 period from one another according to a position on a straight line or a rotation angle of a subject to be detected. Then, the light waves thus subjected to the intensity modulation are coupled to a single transmission optical fiber through the branched optical paths and transmitted to the control unit through the transmission optical fiber. In the control unit, the modulated light wave is received and subjected to the phase detection, thereby to calculate and output the position and the rotation angle in accordance with the phase modulation amount of the received light wave.

摘要： An irregular pattern input device includes an optical fiber bundle in which an entrance surface and an exit surface are respectively formed at both ends thereof. Lighting means emits irradiation light so as to provide a light pattern according to a convex portion of a subject in contact with the entrance surface, and according to a concave portion of the subject in no contact with the entrance surface. In this case, an angle of incidence of the irradiation light is set to be larger than a critical angle on an interface between a core portion of each optical fiber of the optical fiber bundle and the air. It is thereby possible to provide total reflection on the entrance surface in no contact with the concave portion of the subject, and non-total reflection on the entrance surface in contact with the convex portion of the subject, resulting in reflected light having a light pattern according to an irregular pattern. The resultant light pattern is inputted into photoelectric transforming means through the exit surface, and is transformed into electric information by the photoelectric transforming means.

摘要： In a two-color (ratio) or dual-wavelength radiant-temperature measurement, when a bright stray-light source in which its light intensity varies depending on time exists near an object to be measured, by removing an influence caused by the stray light, temperature of the measuring object is measured.By including a main detection unit 51 for measuring, with respect to light from the temperature-measuring object onto which the stray light is added, variation in light intensity versus time in two wavelength bands, and a subordinate detection unit 52 for measuring variation in stray-light intensity versus time only, a temperature calculation unit 70 is provided so that, the varied amounts are extracted, corresponding to superimposed pulses added onto a light-source's drive current, from measured results of the main detection unit 51 and the subordinate detection unit 52; an influential component caused by the stray light is estimated based on a ratio between the varied amounts of both the measured results corresponding to the superimposed pulses; and then, from a measured value in which the influential component caused by the stray light is removed from the measured light intensity values in the two wavelength bands, the temperature of the temperature-measuring object is calculated based on the dual-wavelength radiant-temperature measurement method.
