Abstract

A novel optical approach to single-shot chemical imaging with high spectroscopic resolution is described using a prototype dimension-reduction fiber-optic array. Images are focused onto a 30 X 20 array of hexagonally packed 250- micrometers o.d. f/2 optical fibers which are drawn into a 600 X 1 distal array with specific ordering. The 600 X 1 side of the array is imaged with an f/2 spectrograph equipped with a holographic grating and a CCD images and deconvolute them into wavelength-specific reconstructed images or position-specific spectra which span a 190-nm wavelength space. 'White-light' zero-order images and first- order spectroscopic images of laser plumes have been reconstructed to illustrate proof-of-principle.
