摘要： An optical communication system may include a light transmission unit transmitting a light beam having a first polarization, a quarter waveplate to receive the light beam and to modify the light beam to have a second polarization, and a retroreflector to receive the light beam from the quarter waveplate and reflect the light beam to the quarter waveplate, which modifies the light beam to have a third polarization. The optical communication system may also include a half waveplate to modify the first polarization such that the first polarization is about 90 degrees rotated compared to the third polarization, and a polarizer to pass the light beam having the third polarization and to block most of the light beam having the first polarization.

摘要： A system for determining the spatial orientation of a movable apparatus includes at least one optical angle-of-arrival (OAOA) sensor array, each of which comprises multiple OAOA sensors arranged to provide a 360° field-of-view (FOV). At least one sensor array is mounted on and has a known spatial relationship to a movable apparatus, the spatial orientation of which is to be determined. Point sources are located at one or more stationary positions within the FOV of at least one of the mounted arrays. An initial-north-finding/initial-vertical-finding (INF/INV) system determines the spatial orientation of at least one of the point sources. Processing circuitry coupled to the INF/INV system and the sensor arrays derives the spatial orientation of the mounted arrays—and thereby the spatial orientation of the apparatus—based on the angular positions of the stationary point sources detected by the mounted arrays.

摘要： An optical angle of arrival measurement system uses an optical element to form at least one narrow width line on a focal plane array (FPA) which is oblique with respect to the FPA's row and column axes and which traverses at least two rows or columns along its length; forming two perpendicular narrow width lines in a cross-pattern is preferred. Interpolating the position of the lines on the FPA provides coordinates that can be used to calculate the optical angle of arrival in accordance with θx=A(x)·tan−1(x/f), and θy=B(y)·tan−1(y/f), where f is the focal length of the optical element, and A(x) and B(y) are parameters that account for optical distortion and other imperfections of the system. The resolution δθ of the angle of arrival measurement can be improved to at least δθ˜(d/n)/f, where d is the FPA pixel width and n is the length in pixels of the imaged line.

摘要： An optical tracking system comprises an array of point source emitters that output respective optical emissions, and a plurality of angle of arrival sensors. Each sensor comprises one or more optical elements and a focal plane array (FPA), with the optical elements arranged to resolve the optical emissions into one or more linear patterns on the FPA. A processing system in communication with the sensors establishes the orientation and position of each of the optical emitters using the linear patterns. A headgear tracking system employs point source emitters on a piece of headgear, with front and rear arrays of angle of arrival sensors located in an aircraft cockpit; a processing system in communication with the sensor arrays establishes an orientation and position for each of the optical emitters on the headgear.

摘要： An angle absolute encoder comprises a code rod encoded with code marks configured in segments, such that each successive segment has an increasing number of code marks, arranged at an angle to the rotation axis depending on the number of code marks in each segment. The angle of the code mark is determined by the number of code marks in the respective segment, the width of the segment parallel to the rotation axis of the code rod and the radius of the code rod. The angular resolution increases according to the number of code marks in each segment. Light is reflected from or transmitted through the code marks and detected by a light detector to determine absolute angle position.
