摘要： A laser spot tracker comprising a quadrant detector. A portion of a spot of laser light reflected from an object being illuminated (OBI) may be defocused to occupy a significant portion such as one-third of the field of view, while another portion remains focused, therefore allowing for quick calculation of the spot centroid. With such a “composite spot”, multiple target (OBI) positions may simultaneously be defined in elevation and azimuth with respect to null by analyzing the energy in each quadrant. The X and Y angle information (off null) for multiple targets (OBIs), and their codes may be displayed. For a large, defocused spot, two segmented multi-element detectors may be used, one in front of and the other behind the focal plane to reduce the effects of hot spots in a spot of laser light collected from an object being illuminated.

摘要： A light sensor and light sensing system to detect an intensity of incident light and an angle of incidence of the incident light. The light sensor includes a dielectric layer, a plurality of photo detectors coupled relative to the dielectric layer, and a plurality of stacks of opaque slats embedded within the dielectric layer. The dielectric layer is substantially transparent to the incident light. The photo detectors detect the incident light through the dielectric layer. The stacks of opaque slats are approximately parallel to an interface between the dielectric layer and the photo detectors. The stacks of opaque slats define light apertures between adjacent stacks of opaque slats. At least some of the stacks of opaque slats are arranged at a non-zero angle relative to other stacks of the opaque slats.

摘要： A laser beam and a servo beam are incident on a mirror and a transparent member, respectively, so that an angle direction A1 from an optical axis of the laser beam to be incident on the mirror to an incidence plane of the mirror and an angle direction A2 from an optical axis of the servo beam to be incident on the transparent member to an incidence plane of the transparent member are opposite to each other. With such layout of an optical system, scan loci of the servo beam corresponding to respective scan lines become closer to parallel. In the incidence plane and the outgoing plane of the servo beam of the transparent member, fine periodic structures tapered from the incidence plane and the outgoing plane are formed at pitches each equal to or less than a wavelength band of the servo beam. By this periodic structure, reflection of the servo beam on the incidence plane and the outgoing plane is suppressed.

摘要： Various systems and methods for estimating the position of a radiation source in three-dimensional space, together with sensors for use in such systems are described. In some embodiments, the systems include a plurality of radiation sensors. The three-dimensional position of the radiation source is estimated relative to each sensor using an aperture that casts shadows on a radiation detector as a function of the incident angle of the incoming radiation. In some embodiments, the ratio of a reference radiation intensity to a measured radiation intensity is used to estimate direction of the radiation source relative to the sensor. When the angular position of the radiation source is estimated relative to two sensors, the position of the radiation source in three dimensions can be triangulated based on the known relative positions of the two sensors.

摘要： An optical positioning apparatus and method are adapted for determining a position of an object in a three-dimensional coordinate system which has a first axis, a second axis and a third axis perpendicular to one another. The optical positioning apparatus includes a host device which has a first optical sensor and a second optical sensor located along the first axis with a first distance therebetween, and a processor connected with the optical sensors, and a calibrating device placed in the sensitivity range of the optical sensors with a second distance between an origin of the second axis and a coordinate of the calibrating device projected in the second axis. The optical sensors sense the calibrating device to make the processor execute a calibrating procedure, and then sense the object to make the processor execute a positioning procedure for determining the position of the object in the three-dimensional coordinate system.

摘要： The invention relates to a system for determining a position by emitting a first laser beam (7) by a laser source (6) positioned in a reference system onto a detector (1) and simultaneously detecting the first laser beam (7) by the detector (1), thus defining an emission direction of the laser source (7). The detector (1) has a segmented detection area comprising a plurality of discrete partial detection areas (17), each having a defined partial detection direction and at least two partial detection directions thereof being different. When detecting the first laser beam (7), an impingement point (9) of the first laser beam (7) on the detector (1) is detected by means of at least one partial detection area (17), and when determining the incidence direction (10), said direction is derived from the at least one partial detection direction. The location of the detector (1) relative to the laser source (6) and the reference system is then determined using the emission direction and the incidence direction (10).

摘要： A separation from at least one and an image of at least three reflective regions on the orientation indicator are recorded by a separation measurement sensor and an image sensor in a measuring device, for the purpose of determining the orientation of an orientation indicator. The separation measurement and image recording are achieved by means of a directed emission of a collimated first beam and a divergent second beam with differing wavelengths and/or polarization in the direction of the orientation indicator and a simultaneous recording of the reflected and/or scattered first and second beams. The reflective regions on the orientation indicator are embodied and arranged such as to be positioned at a target point with a detectable geometric relationship to each other and to be simultaneously resolved by the image recorder. By means of the orientation determination, amongst other things, separations from target points, even not directly visible, can be precisely determined.
