Hyperspectral Imaging What is it? How does it work?

Hyperspectral imaging has grown increasingly popular over the past ten years in military, industrial, and scientific arenas. The ability to precisely characterize the color of a viewed item, whether a camouflaged vehicle, a bruise on an arm or on fruit, or a wide swath of vegetation, allows the user to make informed decisions only dreamed of in the past. What once required large, delicate, and expensive laboratory spectrometers is now being done in real time aboard satellites, unmanned aerial vehicles, and portable handheld units.

Product of the Month: The APN Series Power Monitoring Sensor

NK Technologies, San Jose, CA, has introduced the APN Series power monitoring sensor that measures three phases of current and voltage, and computes 14 values necessary to track power usage in the RS-485 Modbus RTU format. The monitor uses current transformers to measure the amperes. The line voltage connects directly to the transducer, up to 600 VAC. The unit’s RS-485 Modbus RTU format is compatible with many programmable logic controllers, and fits into industrial communications networks, both hard-wired and wireless, depending on the application. It can be configured to accept standard 5-amp current transformer inputs or sensors producing 333 mVAC proportional to the AC current of the circuit. The primary circuit voltage is connected directly to the monitor for 600 VAC or lower, or through a potential transformer for monitoring circuits of higher potentials. The APN is powered from an external supply, and provides a pulse contact to open and close as Watt hours are accumulated.

Collaborative Platforms Aid Emergency Decision-Making

Real-time data from NASA satellites enables public agencies to better prepare for natural and manmade disasters. NASA runs and partners in many missions dedicated to monitoring the Earth, and the tools used in these missions continuously return data on everything from shifts in temperature, to cloud formation, to pollution levels over highways. The data are of great scientific value, but they also provide information that can play a critical role in decision-making during times of crisis. Real-time developments in weather, wind, ocean currents, and numerous other conditions can have a significant impact on the way disasters unfold.

Quadrant Photodiode

Opto Diode (Newbury Park, CA) has introduced the SXUVPS4C, a quadrant photodiode with a 5 mm2 active area in each quadrant. The new device is the first of two new SXUV multi-element photodiodes to be introduced. The TO-5 windowless package features a 5-pin header. With light responsivity from 1 to 1000 nm and a shunt resistance of 100 Mohms, the new quadrant photodiode is ideal for 2 axes-positional-centering applications for lasers in the 13.5 nm to 200 nm wavelength range. Operating and storage temperatures range from -10 degrees C to 40 degrees C (ambient) and from -20 degrees C to 80 degrees C (in nitrogen or vacuum conditions). The maximum junction temperature is 70 degrees C and the lead-soldering temperature is 260 degrees C at 0.080 in. from the case for 10 seconds.
