Project Title: An Infrared Microspectroscopy Imaging System

Technical Abstract (Limit 200 words)

With the advent of tunable mid-infrared lasers it now becomes possible to capture spectral data using IR detector arrays. The resulting images would provide a spatial map allowing measurement of optical absorption, reflection or transmission as a function of avelength. We propose to exploit this capability by developing a new infrared microspectroscopic imaging system (IMIS) that provides both high spectral and spatial resolution. Such a system could be used to characterize the spatial variations in a specimenís chemical structure, detect the presence of contaminants, and provide very sensitive surface displacement measurements using an optical technique known as shearography. The proposed system would consist of a tunable mid-IR laser configured for the 1.4 to 5.0 micron wavelength range and a high-resolution, long-working-distance thermal analysis microscope capable of 10-micron resolution.

Potential Commercial Applications (Limit 200 words)

Potential commercial applications include identification and control of contaminates during manufacturing processes such as semiconductor fabrication, observing chemical and structural changes in polymers and paints during the cure cycle, monitoring the ply-to-ply or fiber-to-matrix bond quality in composite materials, measuring oxidation rates and identifying oxidation products, and measuring the relationship between temperature and chemical reaction rates.
