3D Machine Vision Using Laser Triangulation

Applications for 3D machine vision are rapidly expanding in a variety of industries for several reasons. The first is that vision systems can lower production costs by increasing yields and/or reducing scrap product and wasted raw material. One example of this would be extruded products from various materials (rubber, plastic, metal), where it’s vital to know as soon as the process goes out of specification.

Hyperspectral Sensing for Defense and Security Applications

The successful exploitation of hyperspectral imaging sensors depends on the availability of accurate and complete spectral signature libraries. Coupled with the appropriate spectral signature library, images collected with hyperspectral sensors provide the means to survey large areas identifying and characterizing materials, detecting a wide range of camouflaged targets, and detecting disturbed surfaces.

High-Performance Data Acquisition on USB

A common belief among engineers is that in order to get the best performance, a PC-based data acquisition module must plug into the PCI bus. Properly implemented, however, a data acquisition module can use the PC’s USB port to pump data into a PC as fast as PCI-based cards. The keys to achieving this performance are a hardware USB interface on the module, and optimized driver software for the host system.

Generating Broadband Terahertz Radiation from Microplasma in Air

Researchers at the University of Rochester’s Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. Fabrizio Buccheri and Xi-Cheng Zhang recently demonstrated that an approach for generating terahertz waves using intense laser pulses in air – first pioneered in 1993 – can be done with much lower power lasers, a major challenge until now.

Scientists Use X-Ray Laser to Track Ultrafast Creation of a Catalyst

An international team has, for the first time, precisely tracked the surprisingly rapid process by which light rearranges the outermost electrons of a metal compound and turns it into an active catalyst – a substance that promotes chemical reactions. The research, which was performed with an X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory, could help in the effort to develop novel catalysts to efficiently produce fuel using sunlight.
