Methods and systems for adaptively controlling the illumination of a scene are provided. In particular, a scene is illuminated, and light reflected from the scene is detected. Information regarding levels of light intensity received by different pixels of a multiple pixel detector, corresponding to different areas within a scene, and/or information regarding a range to an area within a scene, is received. That information is then used as a feedback signal to control levels of illumination within the scene. More particularly, different areas of the scene can be provided with different levels of illumination in response to the feedback signal.

A dual-polarized antenna array is disclosed. The antenna array includes a plurality of self supporting, electrically conductive members. Tapered elements of neighboring electrically conductive members define tapered slots that form part of radiating structures. The radiating structures additionally include a slot line in communication with the tapered slot. A back cavity can be included as part of a BALUN structure that is integral to an electrically conductive member.

A pulse data recorder system and method are provided. Upon the arrival or occurrence of an event or signal, the state of a digital switch is set. Upon receiving a pulse from a readout clock, the state of the switch is stored in a buffer memory, and the state of the switch is reset. As the readout clock is run, a time history of the state of the switch is obtained. The pulse data recorder can feature a plurality of unit cells, for use in imaging or other multiple pixel applications.

Inside NASA's Goddard Space Flight Center's massive Class 10,000 cleanroom in Greenbelt, Md., the ninth flight mirror has been installed onto the telescope structure with a robotic arm. This marks the halfway completion point for the James Webb Space Telescope's segmented primary mirror. The James Webb Space Telescope team has been working tirelessly to install all 18 of Webb's mirror segments onto the telescope structure. "The years of planning and practicing is really paying dividends and the progress is really rewarding for everyone to see," says NASA's Optical Telescope Element Manager Lee Feinberg. The engineering team used a robotic arm to lift and lower the hexagonal-shaped segment that measures just over 4.2 ft. across and weighs approximately 88 lbs. After being pieced together, the 18 primary mirror segments will work together as one large 21.3-ft. mirror. The full installation is expected to be complete early in 2016. The mirrors were built by Ball Aerospace & Technologies Corp., in Boulder, Colo. Ball is the principal subcontractor to Northrop Grumman for the optical technology and lightweight mirror system. The installation of the mirrors onto the telescope structure is performed by Harris Corp. of Rochester, N.Y. Harris Corp. leads integration and testing for the telescope. The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, ESA (the European Space Agency) and the Canadian Space Agency.

A switched beam antenna system is provided. The antenna system includes a plurality of feed elements arranged radially about a center point. A feed switch provides equidistant signal paths between each antenna element and a transceiver. The production of an antenna beam in a desired direction is achieved by controlling a switch to selectively operate a feed element associated with a beam coverage area that encompasses the desired steering angle.
