Laser Technology News 2008 p5:

• Caltech bioengineers develop "microscope on a chip"
  August 7, 2008--Super-compact high-resolution microscop fits on a chip to image pathogens in the field for cheap.
• Microsoft develops high-efficiency pixel technology
  August 6, 2008--A new type of pixel technology invented by researchers at Microsoft Corporation (Redmond, WA) and the University of Washington (Seattle, WA) for transmissive flat-panel displays increases the backlight transmission efficiency by a factor of 3 to 10 over ordinary liquid-crystal-display (LCD) pixels.
• Molecule-destroying pulses help characterize nanostructured surfaces
  July 30, 2008--Surface-enhanced Raman scattering can be used to detect deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage. To further improve the technique's sensitivity, scientists must design better scattering surfaces, and more effective ways of evaluating them.
• Scientists demonstrate highly directional semiconductor lasers
  July 28, 2008--Innovative lasers have potential in a wide range of photonics and communications applications, say Harvard and Hamatatsu researchers.
• Spectra of quasar accretion discs separated from surrounding nebulosity
  July 24, 2008--Astronomers used polarizing filters to discern the characteristic blue emission spectra of quasar accretion discs from the surrounding clouds. The observations at the Very Large Telescope reconciles quasar observations with models.
• OSRAM makes quantum leap in white LED brightness and efficiency
  July 22, 2008--By improving all the technologies involved in the manufacture of light-emitting diodes (LEDs), OSRAM (Santa Clara, CA) development engineers achieved new records for the brightness and efficiency of white LEDs in the laboratory. Under standard conditions with an operating current of 350 mA, brightness peaked at a value of 155 lm, and efficiency at 136 lm/W.
• Laser scanner helps produce flight simulator ejection seats
  July 21, 2008--Fain Models uses NVision's handheld laser scanner to produce accurate copies of jet fighter ejection seats for use in the flight simulation and training markets for significantly less than the cost of the flight worthy seat.
• Scientists measure ice crystals in clouds using scattered light
  July 21, 2008--New optical scattering technology determines shape and size of ice particles down to microns in size. Knowing the optical properties of ice crystals in clouds can help with climate change predictions.
• LaserMotive tests its climber for the 2008 Space Elevator Games
  July 16, 2008--LaserMotive (Seattle, WA), a company specializing in laser power beaming technology, says that it has successfully tested its first climber prototype for its entry in the 2008 Space Elevator Games.
• Production optical lithography equipment accomplishes the seemingly impossible
  July 16, 2008--Imagine a camera that takes photos containing half a trillion pixels. Such a camera exists, in the form of a semiconductor optical lithography tool called the Twinscan XT:1950i, which creates single-exposure images 22 x 33 mm in size with a 38 nm resolution in photoresist on a silicon wafer, for a total pixel count of 503 gigapixels.
