摘要:
A solar tracking system and method that use a tube that admits solar radiation and one or more photodetectors for generating a signal related to an intensity of solar radiation at a distal end of the tube. The system has a scan unit for periodically executing a certain scan pattern in an elevation angle El and in an azimuth angle Az of the shielding tube. A processing unit in communication with the photodetector determines an on-sun orientation of the shielding tube based on a convolution of the signal obtained while executing the scan pattern with a trained convolution kernel. The on-sun orientation thus found can be used to update the orientation of one or more solar surfaces, e.g., reflective or photovoltaic surfaces.

A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.

The aircraft includes a fuselage and at least one aerodynamic interface surface. It further includes a gimbaled mirror system which includes a mirror supported by a gimbal to receive a light beam from a light emitting source and reflect the light beam to a first periscope fold mirror. A wave front measuring system includes at least five reflective which reflects the light beam to a fast steering mirror. The fast steering mirror reflects the light beam directly to a beam splitter wherein the light beam is split into a transmitted portion and a reflected portion of the light beam.

A dual-mode active and passive gimbaled optical system including a mechanism for coupling an optical signal from an off-gimbal active-mode source into the on-gimbal passive-mode optical path. One example of the system includes a passive off-gimbal detector assembly configured to image emissive electromagnetic radiation from a viewed scene, and a receiver-path optical assembly, including on-gimbal objective optics, that directs the electromagnetic radiation to the off-gimbal detector assembly. The system further includes an off-gimbal active source that generates an optical signal, a gimbal bearing assembly that supports rotation of the gimbal and includes a centrally-located output ferrule mated to an optical fiber that transports the optical signal from the active source to the output ferrule, and an on-gimbal optical coupling element that receives the optical signal from the output ferrule and couples the optical signal into the receiver optical path to direct the optical signal toward the on-gimbal objective optics.

摘要:
A dimensional measuring device sends a beam of light to a remote probe having a retroreflector and a pitch/yaw sensor. The pitch/yaw sensor passes the light through an aperture and a lens to a position sensor that generates an electrical signal indicative of the position of the received light. A processor uses the electrical signal to determine a pitch angle and a yaw angle of the remote probe.
