摘要： PROBLEM TO BE SOLVED: To provide an optical sensor 1 capable of generating a light beam 7 reflected on an object surface 13 to be detected by a detector, using a main light source 5 operated with matched timing. SOLUTION: A compensating light source 25 emits an optical circular cone including a scattered light area of the light beam 7 from the main light source 5 to restrain a disturbance action having the risk caused by scattered light of the light beam 7, during an emission-interrupted period of the main light source 5. An object within the scattered light area generates a component against the compensating light, and the component prevents a sensor output from being driven wholly by the scattered light of the light beam 7.

摘要： PURPOSE: To dispense with an optical element such as beam splitter, and provide a distribution with a desired luminance on the detecting surface of an optical detector by providing a microstructure pattern on the reflecting type optical disc of an optical encoder, and taking out a reflected light having a prescribed order of the light obliquely incident on the optical disc from a light source vertically to the optical disc by use of a diffracting optical element. CONSTITUTION: The diffracted light having a prescribed order of the reflected light of a light obliquely incident on a reflecting type optical disc M having a microstructure pattern on the surface from a light source L is taken out vertically to the optical disc M by a diffracting optical element DOE, and made incident on the detecting surface of an optical detector R. In order to prevent the crosstalk between tracks, a honeycomb-like separator C is arranged between the diffracting optical element DOE and the optical detector R.

摘要： PURPOSE: To obtain an accurate distance measuring apparatus by a constitution wherein the radiation diffused from an irradiated light spot is focused through a focus means and two photodetectors are arranged in the converged beam thereof. CONSTITUTION: A light spot 12 is projected onto an object 11 from a laser light source 62 through a hollow mirror 61 and a diffused radiation is produced as shown by a beam flux 33. A part of the beam flux 33 enters into a distance measuring apparatus 20 and focused 33' one-dimensionally through a mirror 61. The light source 62 is set in the optical axis 16 along with two photodetectors 28, 28' through arrangement of a split mirror 26 wherein the detector 28' is set in the focal line 63 of mirror 61. The detectors 28, 28' are dimensioned to detect all unfocused beams incident on the apparatus 20 one- dimensionally. Consequently, a desired distance can be calculated according to an expression specified by the functional link between each signal and the distance from the light spot 12 on the object 11.

摘要： PURPOSE: To detect and evaluate a rim part of an object or a plurality of rim parts of an object in a non contact method. CONSTITUTION: A work face A is scanned by focused light beam, typically laser beam emitted from a light source L at 40-45 degrees. A first and a second detector D1, D2 receive reflected light from the work face A. The first detector D1 is installed behind a focusing imaging optical system O, e.g. off axis parabolic mirrors arranged coaxially, in other words all are arranged in the surrounding of laser beam, or under light beam emitted in relation to the main work face H. The second detector D is placed approximately on light spot formed by light emitted to the main work face. The stray light measured by the first detector D1 is received at a prescribed angle to the main work face and the angle is equal to the angle between the emitted light and the plane face or smaller than that.

摘要： The proposed method of suppressing interference using a band-pass filter circuit on the receiving side of an optical sensor is based on the assumption that the band-pass filter does not necessarily require a continuous signal and that it may be sufficient to feed the required energy into the filter in the form of short pulses whose repetition period matches the filter's natural frequency. Doing so causes the band-pass filter to resonate like an oscillating circuit, provided that it is of sufficiently high quality. If this is done, the usable signal is boosted while interference of a frequency other than band-pass filter's centre frequency is markedly attenuated. The optical sensor which is used for implementing the proposed method has one or more band-pass filters connected in series, the highest quality filter always being connected at the end of the series. It is advantageous to realize the active band-pass circuit using switched-capacitor technology.________

摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive transmission light barrier ensuring equivalent detection at low fixing cost by improving a transmission light barrier exhibiting two functions in parallel. SOLUTION: The light barrier has a transmitting/receiving part SE and a reflector part R and a transmitter S and a receiver E are arranged in one plane while spaced apart from each other. The reflector part R is provided with reflective elements S1, S2, S3 such that a light beam L1 radiated from the transmitter S is reflected and a return beam L2 is formed. The beam L2 is in parallel with the beam L1 and impinges on the receiver E. The reflector part is provided with the reflective elements S1, S2, S3 such that the transmitting S and receiving E are bridged with a mirror having three parts being constituted of the reflective elements S1, S2, S3 and the first barrier beam L1 is reflected as a second parallel beam L2 at a corresponding interval. When one and/or the other beam is interrupted, the light beam radiates a switching signal.
