High-Speed Laser Scanner Maps a Surface in Three Dimensions

Surface flaws can be scanned automatically and displayed in real time. Ames Research Center, Moffett Field, California A scanning optoelectronic instrument generates the digital equivalent of a three-dimensional (X,Y,Z) map of a surface that spans an area with resolution on the order of 0.005 in. (≈0.125mm). Originally intended for characterizing surface flaws (e.g., pits) on space-shuttle thermal-insulation tiles, the instrument could just as well be used for similar purposes in other settings in which there are requirements to inspect the surfaces of many objects. While many commercial instruments can perform this surface-inspection function, the present instrument offers a unique combination of capabilities not available in commercial instruments.

MALDI and Biotech Push Nitrogen Laser Development

The nitrogen laser is experiencing new growth due to low cost and the MALDI technique. Stanford Research Systems, Sunnyvale, California The Matrix Assisted Laser Desorption and Ionization (MALDI) technique in 1987 led to a renewed interest for the nitrogen laser. MALDI allows large and fragile biomolecules to be desorbed and ionized intact, or with much less fragmentation. The technique increased the upper mass limit for mass spectrometric analyses of biomolecules to over 300,000 Da, and has enabled the analysis of large biomolecules by mass spectrometry to become easier and more sensitive.

Electro-Optical Imaging Fourier-Transform Spectrometer

Size, weight, and vibration are reduced by eliminating moving parts. NASA’s Jet Propulsion Laboratory, Pasadena, California An electro-optical (E-O) imaging Fourier-transform spectrometer (IFTS), now under development, is a prototype of improved imaging spectrometers to be used for hyperspectral imaging, especially in the infrared spectral region. Unlike both imaging and non-imaging traditional Fourier-transform spectrometers, the E-O IFTS does not contain any moving parts. Elimination of the moving parts and the associated actuator mechanisms and supporting structures would increase reliability while enabling reductions in size and mass, relative to traditional Fourier-transform spectrometers that offer equivalent capabilities. Elimination of moving parts would also eliminate the vibrations caused by the motions of those parts.

Product of the Month: Infrared Camera

Mikron Infrared (Oakland, NJ) offers the Model M7500 infrared camera configurable for midwave or long-wave imaging and four different temperature bands. The camera is an uncooled microbolometer camera that features spectral tuning technology. It can image in the mid-wave bands of 3.9 μm and 4.8 to 5.2 μm, in a temperature range of 400 to 1600°C. The camera has two temperature ranges of -40 to 120°C, and 50 to 500°C in 8 to 14 μm long-wave mode for thermal monitoring applications. An 8 to 14 μm high-temperature version provides a range of 200 to 2000°C.

Multispectral Imaging System

The SATIR system from Cedip Infrared Systems (Croissy, France) is designed for infrared analysis of targets on air, sea, or land. Designed to provide outdoor IR radiometric measurements, the system enables operators to collect and store in real time synchronized sequences of images from the three main infrared wavebands: 1-2.5, 3-5, and 8-12 microns. The system uses IR focal plane array detector technology and ultrafast processing electronics, and is mounted in a ruggedized enclosure. The system comprises three IRFPA cameras, each one connected to a single computer for real-time storage. A PC server controls each camera PC and provides image processing. All images taken on the SATIR are referenced with time and location through a GPS receiver. Software provides processing and analysis of IR images and sequences of images.
