' - Bill Webster, head of the Technology Transfer Office Wire-grid polarizers hold promise for use in military and private applications By CUffLawson TID W ire-grid polarizers aren't something you see every day, and most ofus wouldn't recognize one ifwe did. But the tiny devices are a critical part ofcertain Navy optical systems and are also the subject of a recently signed cooperative research and development agreement (CRADA) between NAWCWPNS and Leonard Research Corp. (LRC) of Beavercreek, Ohio. To understand how a polarizer works, think oflight as a wave with peaks and troughs - actually electrical field vectors - radiating out in all directions from the direction ofpropagation. The polarizer acts as a screen that allows only a narrow segment of the vectors through; i.e., those that are oriented in a specific plane. A wire-grid members of the Research and Technology Group are working to integrate a wire-grid polarizer with a charge-coupled device sim- ilar to those used in missile FPAs. Commercial optical polarizer applications range from glare- reducing sunglasses to special coatings for surveillance-camera lenses to make them less obtrusive. Polarization is also used in the radio frequency spectrum to exploit the limited bandwidth available on communications satellites. Through "frequency reuse," an antenna can simultaneously transmit adjacent beams at the same frequency. By polarizing each beam differently, beam isolation is maintained. The LRC/NAWCWPNS CRADA grew out of a 1991 small business innovative research (SBIR) program managed at China Lake. Dr. Tom Leonard, now CEO of LRC, was part of a team that designed and built a unique optical-element characterization instrument. China Lake researchers used the device, called the Automated Trans- mission/ Contrast Instrument (ATCI), to map contrast ratios and contrast efficiency of large- area glass polariz- ers. polarizer consists of extraordinarily thin ribbons, each less than a micron (0.0039 inch) in width, running par- allel to each other. When radiation, such as visible or infrared light, strikes the grid, most of it is reflect- ed. Only a selective- ly polarized portion of the radiation passes through the grid. The grid is very dens&-50,000 ribbons per inch is not uncommon- because the ribbons must be closer than the wavelength of the radiation being examined.

In 1995 China Lake began an internal program to develop micro- electro-mechanical (MEM) devices. One of the applica- tions of MEM devices is the fabri- cation of wire-grid polarizers. Blazek, a MEM team mem- ber, had been involved with the earlier SBIR and realized that the ATCI, with some modification, would be useful for characterizing the MEM-fabricated reflected from an object, scientists can extract a great deal of information about the physical and chemical makeup of its sur- face, which explains part of the military's interest in polarizers. China Lake is particularly interested in using wire-grid polariz- ers in optical target-detecting devices and focal-plane array (FPA) detectors for missile seekers. ''Incorporating wire-grid-polarizer technology in target-dis- crimination systems is a gradual process," says Hank Blazek, an electronics engineer in the Engineering Materials Section of NAWCWPNS Research and Technology Group. "It requires a progression of refinements and developments." Currently, other polarizers. Thus was the new CRADA conceived. Like all CRADAs, this one emphasizes cooperative endeavor and mutual benefits. China Lake is providing the government- owned ATCI to LRC along with samples of the wire-grid polar- izers for measurement. LRC is modifying the ATCI software and hardware and optimizing it for wire-grid-polarizer measurement and characterization. The enhancements implemented by LRC will become part ofthe commercialized variant ofthe ATCI. "The ATCI can do more than analyze polarizers," notes Leonard.
