PROPOSAL NUMBER : 96-1 12.01-1774

PROJECT TITLE : : Tunable, Variable Bandpass, Holographic Optical Filter

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

This Small Business Innovation Research phase I project aims to develop and produce a fast tunable and variable bandpass optical holographic optical filter for radiometer imaging. Holographic Optics, Inc. proposes to develop techniques which will make existing holographic recording materials tunable by inducing dimensional changes in the grating structures of the holographic filter. Changing the grating spacing the frequency response will shift to lower wavelengths. And by tuning simultaneously two or more of these grating structures a spectral window of variable bandpass will be obtained in real time. Some advantages of holographic filters include polarization independence, high efficiency, narrow bandwidth, high transparency, wide spectral range and multiple wavelength capability. Additionally, they can be mass produced cost effectively. This research aims to retain these desirable characteristics while adding the tunability feature.
POTENTIAL COMMERCIAL APPLICATIONS
The proposed research will lead to a fast tunable and variable bandpass optical filter which can be used in application such as high capacity optical communications systems, optical measurements instruments, filters for agile lasers protection, and new display technologies.
