Briefs: Test & Measurement
The shapes of waveforms generated by commercially available analytical separation devices, such as some types of mass spectrometers and differential mobility spectrometers are, in general, inadequate...
Briefs: Test & Measurement
An alternative approach to apertureless near- field optical spectroscopy involving an atomic-force microscope (AFM) entails less complexity of equipment than does a prior approach. The...

Hyperspectral Fluorescence and Reflectance Imaging Instrument
The system is a single hyperspectral imaging instrument that has the unique capability to acquire both fluorescence and reflectance high-spatial-resolution data that is inherently spatially and spectrally registered. Potential uses of this instrument include plant stress monitoring,...
Briefs: Electronics & Computers
A system that comprises optical and electronic subsystems has been developed as an infrastructure for a spectroradiometer that measures time- dependent spectral radiance of the daylight sky,...
Briefs: Physical Sciences
The ultra-stable beacon source (USBS) provides a laser-beam output with a very low angular jitter and can be used as an absolute angular reference to simulate a beacon in the...

Fly-by-Wireless: A Less-Wire and Wireless Revolution for Aerospace Vehicle Architectures
Every ounce of weight brought to the lunar surface costs 40 to 60 times that in fuel needed at liftoff from the Earth. Part of that weight penalty is due to wires, but the cost of wires is much more than weight. Wired connectivity drives up the price of design...

Low-Power, Zero-Vibration Sorption Coolers
A report discusses three designs of proposed low-power, zero-vibration coolers for infrared instruments planned to be flown aboard spacecraft to perform astrophysical observations far from Earth. The designs take advantage of the radiative precooling available in the projected deep-space operational...
Briefs: Materials
Efforts are under way to develop a technique of noncontact acousto-ultrasonic testing in which (1) a pulsed laser beam excites ultrasonic waves in a plate specimen and (2) the ultrasonic...
Briefs: Test & Measurement
A proposed miniature turbomolecular pump would be a prototype of high-vacuum sources for a forthcoming generation of miniature, portable mass spectrometers and other scientific instruments. The...
Briefs: Test & Measurement
Sponsored by a NASA Small Business Innovation Research (SBIR) Phase II contract, MetroLaser, Inc., has developed a novel, compact and low-cost laser Doppler vibrometer (LDV) under the...
