High-Speed Camera

With an exposure time of 200 ps, the OptoPIC camera from Optronis (Kehl, Germany) captures images of objects with rapidly changing light emission. The exposure has a repetition rate of 70 to 110 MHz. The programmable delay allows for shots to be taken automatically at various intervals in order to record a sequence of images which present the rapid changes in light emission in super-slow motion. The camera uses a specially developed image intensifier for realizing the short exposure. Up to three pulsed light sources and a filter wheel can be integrated into the camera as optional extras. Flexible control of the camera is provided via a LabVIEW application.

USB 3.0 Camera

Point Grey (Richmond, BC, Canada) has announced the addition of a new 1.3 MP global shutter CMOS to its Chameleon3® set of USB3 Vision™ cameras. The Chameleon3 CM3-U3-13Y3 models are based on color and monochrome versions of the ON Semiconductor PYTHON1300, a ½" global shutter CMOS sensor featuring 1280 x 1024 image resolution. The camera runs at 149 frames per second (full resolution) and up to 470 (fps) in pixel binning mode. Available in a 44 x 35 x 19.5 mm case or as a 40 x 31 mm board stack, the Chameleon3 includes an on-camera frame buffer for image retransmission and an opto-isolated GPIO with locking connection.

Design and Engineering of Process Plants Based on the “Lego Principle”

Users can add automation modules or switch them off in line with requirements. Festo Corporation, Hauppauge, New York Manufacturers in the process industries need to adjust to smaller batches and different types of product in the same plant. Plants based on the “Lego principle” are designed and engineered precisely to the respective task, whether for the production of a specific product in units per time unit, or for the throughput of a specific substance in a quantity per time unit. The mechanical design of the plant as a whole is geared towards meeting specifications and guaranteeing the required performance data over the projected lifecycle of the plant. The corresponding automation is carried out using management systems comprising process-specific (control) components, operating and monitoring stations, as well as engineering stations. The entire process is centrally controlled by a single management system.

Electrochemically Enhanced Mechanical Polishing of Optics

A combined method results in a significant reduction of manufacturing time for optical components. Marshall Space Flight Center, Alabama Optical component fabrication using metals or ceramic materials involves many grinding and/or machining and polishing steps to achieve the proper form to the tolerances of imaging or photonic focusing instruments. These instruments range from infrared sensors, through visible and ultraviolet, to X-ray and even thermal neutron focusing. Conventional manufacturing methods require many days or even months of precise polishing to improve selected areas of the component.

Expendable Cooling System for Venus Lander Concept

The concept could be applicable to the trucking industry to provide temporary cooling where power is not readily available. NASA’s Jet Propulsion Laboratory, Pasadena, California This innovation is a concept for a novel thermal architecture that would enable a day-long surface mission on Venus. A Venus lander mission could last much longer than a few hours on the surface of the planet by absorbing heat from the Venus environment, and from the electronics within the lander, by using an expendable fluid cooling system. The fluid would evaporate in the structural shell, absorbing heat coming from the ambient environment, keeping the shell relatively cool compared to the ambient temperature. The evaporating fluid would create a liquid flow from a reservoir used to cool electronic components within the lander. The liquid reservoir must be contained within the lander structure to serve as a heat sink to maximize the lander lifetime on the surface. A pressure tank would be used to bring the fluid to a point where it could boil and vent into the Venus atmosphere.
