Paper Abstract

OPTRA is developing a high speed resonant Fourier transform infrared (HSR-FTIR) spectrometer for surface contaminant measurements via time resolved thermal luminescence. This system incorporates a multipass reciprocating interferometer and a resonant mirror structure to accomplish the scanning. The resonant scanning approach significantly reduces the mirror drive power requirement relative to a non-resonant system. Because the spectral range is limited only by the spectral transmission and reflection properties of the components and the detector responsivity, this system can be made as broadband as a typical FTIR spectrometer system. For this application, the system will operate over the 700 - 1400 cm-1 spectral range with 8 cm-1 spectral resolution. This paper presents a portion of the preliminary design of the HSR-FTIR prototype and includes the results from breadboard tests of the resonant mirror assembly.
