Current hyperspectral imaging cameras are typically limited in throughput either by a slit or other optical geometries requiring small solid angle instantaneous fields of view. The high etendue imaging Fourier transform spectrometer optical design is a new optical geometry for the production of spectral autocorrelation fringe modulation over an image plane defined by a large CCD array. A throughput advantage approaching several hundred appears realizable, with an accompanying increase in signal to noise proportional to 'root N'. THe simple optical implementation of this design will be discussed along with initial experimental results.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
