摘要： For evaluating navigation information based on line-of-sight measurements, a method measures a line-of-sight measurement with an imager. The method further calculates an information metric based on the line-of-sight measurement. The information metric is a function of imager pixel measurement noise and a relative position vector for an imager frame aligned with a focal plane frame for the imager. The method evaluates navigation information using the information metric.

摘要： A two-dimensional magneto-optical trap (2D GMOT) that is configured to produce a cold-atom beam exiting the 2D GMOT is disclosed. In embodiments, the 2D GMOT is configured to feed a three-dimensional GMOT with the cold atom beam. In embodiments, the 2D GMOT includes an input light beam having its direction along a first axis, its width along a second axis, normal to the first axis, and a substantially flat input light beam intensity profile. 2D GMOT may further includes a quadrupole magnetic field with its magnitude being zero along a third axis that is centered at the center of the input light beam's width. The 2D GMOT may also include a diffraction-grating surface positioned normal to the first axis, composed of closely adjacent parallel grooves spread across the width and run parallel to the third axis.

摘要： Devices, systems, and methods for dispersive energy imaging are disclosed. The full three-dimensional velocity distribution function of a flowing particle stream may be measured and properties of the particle stream characterized. In some devices, an aperture system controls the entry of a stream of particles into the sensor where an electrostatic deflector separates the stream of particles into different species, and a detector system senses the separated species.

摘要： An OPO is disclosed capable of rapid frequency tuning by non-mechanical means. The OPO includes a resonant cavity including one or more non-linear crystals in an optical path thereof. A pump laser pulse is transmitted into the resonant cavity simultaneously with a seed beam having a desired wavelength. The output beam from the resonant cavity has the same center wavelength as the seed beam. The wavelength of the seed beam may be modulated at a frequency larger than the pulse rate of the pump laser or larger than the inverse of the pulse duration. The OPO disclosed may be used to perform DIAL analysis wherein intra-pulse modulation of an output beam is used to obtain measurements of absorption at multiple frequencies for each pulse of a pump beam.

摘要： A computer implemented method for sensing occupancy of a workspace includes creating a difference image that represents luminance differences of pixels in past and current images of the workspace resulting from motion in the workspace, determining motion occurring in regions of the workspace based on the difference image, and altering a workspace environment based at least in part on the determined motion. The method also includes determining which pixels in the difference image represent persistent motion that can be ignored and determining which pixels representing motion in the difference image are invalid because the pixels are isolated from other pixels representing motion.

摘要： A method for on-orbit calibration of the temperature sensors of a simulated blackbody is disclosed. The method may include selecting a simulated blackbody traveling in a micro-gravity environment and comprising a sensor, a container positioned proximate the senor and containing a material, and a heat transfer device positioned proximate the at least one container. The heat transfer device may transition the material through a phase change. The temperature sensor may monitor the temperature of the material during the phase change. A correction may be calculated to correct any disparity between the temperature reported by the temperature sensor during the phase change and the known plateau temperature corresponding to that phase change. The correction may be applied to subsequent temperature readings obtained using the temperature sensor.

摘要： Disclosed herein are various energy conveyance systems that are able to convey energy along different optical paths to non-overlapping regions of a sensor. A system can include an objective optics system that collects and focuses energy, and can further include steering optics that are configured to divert an optical path of at least a portion of the energy that is collected via the objective optics system. The steering optics may cause different portions of energy collected via the objective optics system to be delivered as focused field images to non-overlapping or similar sections of a sensor.

摘要： A method and system that compensates for thermal induced stresses in structures composed of different materials fastened together. The system utilizes three compensation mounts made from a material with a coefficient of thermal expansion that is between that of the two materials being fastened together. These mounts can be linear or, for a thinner structure, the mounts are “C” shaped. The size of the “C” mounts and fastening locations are calculated based on the coefficient of thermal expansion for the two materials being fastened together and the “C” mount material. The geometry of the “C” mounts allows for fastening the two planar surfaces without introducing a large thickness increase to the structure. This system allows for materials to be fastened together, and when placed in an environment with temperature fluctuations, the system experiences zero, minimal or insignificant amounts of thermal induced stress.
