摘要： PROBLEM TO BE SOLVED: To provide an angle detection device for an oscillation motor precisely detecting the rotation angle without being affected by the fluctuation of light volume or the uneven irradiation light with high utilization efficiency.
SOLUTION: In the angle detection device 10, the circular-arc shaped outer face of the fluorescent fiber 15 is scanned by the scanning beam RB reflected by the scanning mirror 14 fixed with the rotating shaft 13 of the oscillation motor 12. The fluorescent light generated from the part of the fluorescent fiber 15 scanned by the scanning beam RB, is transmitted to the both sides and the light volume corresponding to the scanning position are detected by the photodiodes PD1, and PD2. The signal processing circuit 16 calculates the scanning position of the scanning beam by comparing the output signals of the photodiodes, thereby the rotation angle of the oscillation motor 12 corresponding to the scanning position is found.

摘要： PROBLEM TO BE SOLVED: To provide a quantity-of-displacement-light converter whose sensitivity with reference to the very small displacement due to a sound or the like of a diaphragm can be increased easily. SOLUTION: In the quantity-of-displacement-light converter, the diaphragm 1 is arranged so as to face a light emitting part 2 and a light receiving part 3, light which is emitted from the part 2 and reflected by the diaphragm 1 is received by the part 3, and the displacement of the diaphragm 1 is converted into the output of the part 2. The converter is constituted in such a way that the diaphragm 1 is formed to be a concave shape with reference to the part 2 and the part 3, that the distance between the reflecting surface of the diaphragm 1 is an optical path reaching the part 3 from the part 2 and the part 2 and the part 3 is set at the radius of curvature of the concave shape and that the perpendicular line of the reflecting surface passes between the part 2 and the part 3.

摘要： PROBLEM TO BE SOLVED: To provide a method able to sense direction of rolling (longitudinal or lateral) simply with an apparatus of a small structure. SOLUTION: A rolled plate 16 is irradiated with red light at a specified angle θ of incidence by a light emitting part 10a of a sensor 10 and return light reflected from the plate is received by a photodetecting part 10b. The light is transduced into a voltage by a signal processing part 14a in proportion to the quantity of light detected and the voltage value is outputted to a voltage value display part 14b' of an output part 14b. When the voltage value is large, the lateral rolling is judged as the direction of rolling is orthogonal to the direction of incidence, and when it is small, the longitudinal rolling is judged as the direction of rolling is parallel with the direction of incidence. Such a judgment may be performed by watching a display part with naked eyes. The judgment also may be performed within the signal processing part and the results of the judgment are shown by controlling the lighting of a results of judgment display part (lamp) 14b''.

摘要： PURPOSE:To certainly measure the displacement in the accuracy order of lambda/10-lambda/1,000, by the function relation between the increase and decrease of the light from the total reflecting surface having a concave curved surface provided in opposed relation to an object to be measured and the displacement quantity of the object to be measured. CONSTITUTION:The luminous flux L emitted from a laser beam source 1 transmits through a half mirror 5 to become luminous flux Li which is, in turn, incident to an optical part 2 to be reflected from the total reflecting surface SR thereof. This total reflecting surface SR is formed into a concave spherical surface having a radius R of curvature and the reflected beam becomes luminous flux Lo having an expanse to go toward the first photoelectric sensor 3. The intensity of said luminous flux Lo suddenly decreases along with the approach of an objective body 8 and, in this suddenly decreasing region G, the output voltage Eo of the sensor 3 and an interval (x) almost linearily changes. The luminous flux Lo suddenly decreases since the luminous flux Lo exudes from the reflecting surface SR to a surface SO. Noise is removed from the voltage Eo using the voltage Er obtained by photoelectrically converting the luminous flux Lr branched from the mirror 5 to calculate voltage E and the interval (x) is operated from the straight line showing the relation between the voltage E and the interval (x) to be displayed on a display device 9.
