摘要： The invention relates to an arrangement and a method for measurement on a resonant oscillator with a mirror surface (8), which is displaced about an oscillation axis (2) with a period of duration (T), a laser diode (4) which emits a measuring beam (3) onto the first mirror surface (8), whereby a beam axis (21) of the measuring beam (3) intersects the oscillation axis (2). A photo receiver (6) is arranged opposing the first mirror surface (8) at a separation (a) from the beam axis (21) and a separation (b) from the mirror surface (8). The deflected measuring beam (5) moves within a quarter of a period (0 .... T/4) of an oscillation and over the photo-receiver (6) within a following quarter (T/4 .... T/2) of the period. The photo-receiver (6) is connected to an analytical circuit (11) which calculates the timepoints (t1, t2) from the impulses from the photo-receiver (6) and calculates a time period within the one half-wave (Δt = t2 - t1) from the above. The analytical circuit (11) calculates an actual value of the maximum amplitude with the equation:(I). The time duration Δt corresponds to a line dead time on writing sequential lines of a video image.

摘要： An optical encoder whose light utilization efficiency is high and which can be manufactured easily. The encoder is provided with a converting element (7) having lens elements (71, 72) periodically arranged at predetermined pitches IP so as to convert a luminous flux L from a light source into a plurality of moving luminous fluxes MF. The luminous flux L is collimated to a half of the pitch IP by means of the element (7), emitted as a parallel luminous flux having a width IP/2, and made incident on a light receiving section (4). On the substrate (41) of the section (4), light receiving elements (42) are arranged at pitches of IP/2. When an object coupled to the converting element (7) rotates or translates, the positions of the lens element (71, 72) synchronously change and the array of the light receiving elements (42) is scanned with the moving luminous fluxes MF. As a result, the proportion of the quantity of light arriving at the elements (42) periodically changes. Obtained electric signals are processed by means of a well-known processing circuit.

摘要： The present invention provides a method and an apparatus for detecting a position of a light spot in a light distribution that can include stray light components (e.g. from other lasers, ambient lighting etc.). The apparatus includes a continuous response position sensitive detector (CRPSD, e.g. lateral effect photo-diode) for determining a first centroid of the light distribution and a discrete response position sensitive detector (DRPSD, e.g. multiplexed array) for determining a second centroid of the light distribution within a reading window defined about the first centroid and within the light distribution. The second centroid represents the position of the light spot in the light distribution. This multiple stage approach exploits the high resolution and speed offered by traditional CRPSDs together with the accuracy under variable lighting conditions offered by traditional DRPSDs.

摘要： An optical displacement sensor is disclosed for use in robotic applications. The sensor can be used to examine the shape and surface texture of an object. In the embodiment which includes a compressible means of known spring constant, the sensor can be used to measure contract force. The position sensor uses an electro-optical displacement transducer to convert a displacement into an electrical output. The sensor utilizes a phototransistor to measure light emitted by an infrared light emitting diode. The amount of light received from by the phototransistor is varied by the displacement of the contact probe, or shadow rod.

摘要： A position sensor for monitoring the position of the valve element (7) of a valve is described. The sensor comprises reflector means (2) associated with the valve element (7) and arranged to reflect energy, for example visible light, from a suitable source (3) such that when the valve element (7) is in a first position the reflected energy is incident upon a detector (4). Movement of the valve element (4) away from the first position results in the reflected light no longer being incident upon the detector (4).
The invention further relates to a valve including such a position sensor.

摘要： This invention is directed to providing a rotary encoder which is small in size and free from loose shaft. To accomplish this object, a cylindrical support shaft extending from the bottom surface of a rotary encoder substrate portion fits to and supports a cylindrical operation shaft so that the length of a fitting portion of a knob and that of the cylindrical operation shaft can be elongated, therefore the height of the rotary encoder can be reduced as a whole while limiting the inclination of the knob and the looseness of the fitting portion of the rotary shaft.

摘要： In a position detecting method and an apparatus therefor, a signal processing circuit (22) including a semiconductor laser (34), a light receiving element (20) and the like is arranged on the outside of a servomotor. An article (17) to be detected is arranged within the servomotor. The signal processing circuit (22) and the article (17) are connected to each other by a single or a plurality of optical fibers (33), (37). A laser light is applied to surface properties formed inevitably at processing of a surface (17a) of the article (17), to produce a signal of a reflected light. The signal of the reflected light and a beforehand stored position signal of the article (17) are compared with each other so as to be converted into a rotational-angle signal, thereby detecting a position of the article (17).
