Measure Foundry(R) 5.0 test and measurement software from Data Translation, (Marlboro, MA) was named NTB's Product of the Month for May. The software offers open support of all system standards, including VISA, SCPI, GPIB, USB, PCI, LXI, PXI/VXI, and RS-232. The application builder software enables users to graphically combine various test and measurement instruments without writing code to create process control and data analysis applications. The software uses drag-and-drop components such as oscilloscopes and chart recorders that are placed on a form and then configured with their property pages. For more information, see page 8 of the May issue of NTB or click here.

Tech Needs of the Week

A high-birefringence optical material is needed suitable for implementation in optical systems. The material also should feature high hardness making it amenable to standard polishing and manufacturing processes, low CTE (coefficient of thermal expansion), low CTRI (coefficient of thermal refractive index), low absorption at 1.55 micrometers, and reasonable bulk density. To respond to this Tech Need, click here. A new material is needed that can rotate linearly polarized light. Of further interest is any new material with unique optical characteristics. Such materials may come from new developments in biotechnology, films, coatings, polymer chemistry, mineralogy, metallurgy, or any other field. To respond to this Tech Need click here. The Technology Needs of the Week are anonymous requests for technology, distributed through the yet2.com marketplace, that you and your organization may be able to fulfill. Responding to a Tech Need is the first step to gaining an introduction with a prospective "buyer" for your technology solution.

Laser System

MIT researchers have developed a new type of laser based on Optical Coherence Tomography (OCT) for taking high-resolution, 3D images of the retina. OCT uses light to obtain high-resolution, cross-sectional images of the eye to visualize subtle changes that occur in retinal disease. Conventional OCT imaging typically yields a series of 2D cross-sectional images of the retina, which can be combined to form a 3D image of its volume. The system works by scanning light back and forth across the eye, measuring the echo time delay of reflected light along micrometer-scale lines that, row by row, build up high-resolution images. Commercial OCT systems scan the eye at rates ranging from several hundred to several thousand lines per second. But a typical patient can only keep the eye still for about one second, limiting the amount of 3D data that can be acquired. Using the new laser, the researchers report retinal scans at speeds of up to 236,000 lines per second, a factor of 10 improvement over current OCT technology. Click here for the full story.

Embedded Technology (ET) magazine features board-level electronics and COTS solutions for design engineers, as well as a variety of product offerings. The May issue of Embedded Technology contains a feature article written by Julien Chouinard, managing director at ICS Triplex ISaGRAF (Montreal, Canada), entitled “Distributed Control Standard Connects Industry Regardless of Bus.” The article notes the proliferation of fieldbus networks (such as PROFIBUS, DeviceNET, and SERCOS, etc.) and highlights the implementation of IEC 61499, which created the structure for a supervisory application layer that connects isolated control systems. See page 2 of the May issue for the full article. To read previously published ET articles, cick here.
