Standoff Detection using a Spatial Heterodyne Raman Spectrometer
Demonstrated that the technique works in the visible, and provides high resolution (6 cm-1) Raman spectra with a large spectral range. Much higher resolution is possible. ? Demonstrated the wide-area capability without loss of resolution and minimal loss of intensity. ? Demonstrated with pulsed laser and gated detection for ambient light discrimination. ? Demonstrated standoff capability with and without a telescope. ? Pointed out some key issues that still need to be addressed including stability of optical mounts, quality of optics, anti-Stokes overlap, and the need for excellent bandpass filtering.
