- US scientists make LED fluorescence spectrometer in a
chip-sized version. Bush, Steve; Yeates, Harry // Electronics Weekly;2/25/2004, Issue 2135, p7
Researchers in the U.S. have developed a chip-scale version of a laser fluorescence spectrometer, a standard piece of analytical laboratory equipment that usually occupies a box the size of a photocopier. The work involved developing a technique called 'laser lift-off', which uses a fast excimer...
- The application of quasi-phase-matched parametric light sources to practical infrared chemical sensing systems. Kulp, T.J.; Bisson, S.E.; Bambha, R.P.; Reichardt, T.A.; Goers, U.-B.; Aniolek, K.W.; Kliner, D.A.V.; Richman, B.A.; Armstrong, K.M.; Sommers, R.; Schmitt, R.; Powers, P.E.; Levi, O.; Pinguet, T.; Fejer, M.; Koplow, J.P.; Goldberg, L.; McRae, T.G. // Applied Physics B: Lasers & Optics;2002, Vol. 75 Issue 2/3, p317
Quasi-phase-matched (QPM) materials allow the generation of spectroscopically useful infrared radiation in an efficient and broadly tunable format. Here, we describe several applications of QPM-based light sources to remote and local chemical sensing. The remote systems are gas imagers that...
- Success with Evaporative Light-Scattering Detection. Young, Craig S.; Dolan, John W. // LC-GC Europe;Mar2003, Vol. 16 Issue 3, p132
Provides some tips and techniques on evaporative light-scattering detection (ELSD). Operating principle; Advantages of ELSD; Limitations of ELSD; Troubleshooting of ELSD.
- Sensing an edge with a lateral photodetector. Leung, A. F.; Soderberg, S. // Review of Scientific Instruments;Jan2002, Vol. 73 Issue 1, p23
The electrical response of a linear lateral photodetector to three different light projections is examined. First, one section of the photodetector is illuminated and the rest of the detector is covered with a piece of black tape forming a bright/dark edge. Second, the whole photodetector is...
- Vision sensors need good lights. Titus, Jon // Test & Measurement World;Apr2002, Vol. 22 Issue 4, p53
Discusses reasons why there is a need for inspection engineers to set-up the proper lighting conditions to ensure that a vision sensor can capture a good image. Inability of the characteristics of normal incandescent lights to match those of solid-state cameras; Inability of vision sensors to...
