Abstract: An apparatus may provide a control signal based on an axial position of a controller displaceable along an axis. The apparatus may include a component for displacement with said controller along said axis, a radiation source and detector arrangement configured to direct radiation towards a target region and generate a detector signal dependent upon radiation reflected from within that target region, and a computer processor configured to process said detector signal to determine a measure of distance or change of distance to a reflecting surface region within said target region, and to use said measure to provide said control signal. The component may define a reflecting surface that passes through said target region such that a reflecting surface region is present within said target region with a distance that varies with the axial position of the component along said axis.

Abstract: An optical detection system includes a marker product and an optical encoding device. The marker product includes a substrate and at least one structural portion. The structural portion has a first surface, a second surface and a dividing axis. The first surface and the second surface are arranged on opposite sides of the dividing axis. A sidelong direction aligning the first surface with the second surface is parallel to a moving direction between the optical encoding device and the marker product. The optical encoding device is disposed adjacent by the marker product. The optical encoding device includes an optical projector and an optical encoder. The optical projector is configured to project the optical detecting signal onto the marker product. The optical encoder is configured to receive an optical reflecting signal from the marker product and encode intensity variation of the optical reflecting signal into digital data.

Abstract: A gravimeter, a gravimeter system, and a method for measuring gravitational acceleration within a borehole are described herein. The gravimeter includes a proof mass that is constrained by springs and an optical interferometer for measuring displacement of the proof mass. The optical interferometer generates a light path from a light source to a reflective surface on the proof mass. Spatial displacement of the proof mass from a reference position to a position of gravitational equilibrium is determined by measuring a change in length of the light path. In turn, gravitational acceleration can be determined from the spatial displacement of the proof mass. A number of such gravimeters can be used in a gravimeter system to make measurements of gravitational acceleration in variety of different directions.

Abstract: An optical connection device includes a light source section configured to emit light, a light guide section configured to guide the light emitted from the light source section and including an emitting section configured to emit the guided light to the outside, and a light receiving section configured to receive the light emitted from the emitting section. At least one of the light source section and the light receiving section turns around a turning axis. Therefore, a transmission distance of the light from the light source section to the light receiving section changes.

Abstract: The present invention mainly provides a precision calibration method for being applied in a high-precise rotary encoder system, wherein the primary technology feature of the precision calibration method is that: using a laser speckle image capturing module to capture N frames of laser speckle image from an optical position surface of a rotary encoding body, and then using image comparison libraries and particularly-designed mathematical equations to calculate N number of image displacements, so as to eventually calculate N number of primary variation angles and sub variation angles corresponding to the N frames of laser speckle image. Therefore, after the rotary encoding body is rotated by an arbitrary angle, an immediate angle coordinate can be precisely positioned according to the primary variation angles, the secondary variation angles and the N number of image displacements.

Abstract: An optical position sensing system and method for sensing a gimbal position in a gimbal-based optical system. One example of an optical position sensing system includes an off-gimbal light source that generates a position sensing light beam and transmits the position sensing light beam along an optical coude path of the optical system, and an on-gimbal optical element that causes a change in an intensity of the position sensing light beam based on rotation of the gimbal about the axis. The system further includes an off-gimbal detector configured to receive the position sensing light beam returned from the optical element and to detect the change in the intensity of the position sensing light beam, and a controller coupled to the detector and configured to determine the gimbal position based on a correlation between the change in the intensity of the position sensing light beam and the gimbal position.
