Abstract
A single-frame approach to chemical imaging with high spectroscopic resolution is described that makes use of a second generation dimension-reduction fiber-optic array. Laser-induced plume images are focused onto a 17 X 32 rectangular array of square close-packed 25 micrometers cross- sectional f/2 optical fibers that are drawn into a 544 X 1 distal array with serpentine ordering. The 544 X 1 side of the array is imaged with an f/2 spectrograph equipped with a holographic grating and a gated intensified charge- coupled device (ICCD) camera for spectral analysis. Software is used to extract the spatial/spectral information contained in the ICCD images and deconvolute them into wavelength-specific univariate reconstructed images or position-specific spectra that span an 86 nm wavelength space.
