Brief
This article describes a single-frame chemical imaging spectroscopy technique using a dimension-reduction fiber optic array to simultaneously capture spatial and high-resolution spectral information of laser plumes for time-dependent analysis.
Summary
This article presents a novel single-frame chemical imaging spectroscopy technique that uses a dimension-reduction fiber optic array to capture spatial and spectral information of laser plumes with high spectroscopic resolution. The image of the plume is focused onto a 2D array of optical fibers which are rearranged into a 1D array at the distal end and imaged by a spectrograph with an ICCD camera. Software is then used to reconstruct wavelength-specific images and position-specific spectra, allowing for the study of the temporal evolution of laser plumes. This method enables the acquisition of significant sample information in a single image.
