An imaging spectrometer that can simultaneously obtain 3-D spatial and hyperspectral data has been developed. The Ranging-Imaging Spectrometer (RIS) is based on the Computed Tomographic Imaging Spectrometer (CTIS) developed at the Optical Science Center, and the Scannerless Laser Radar (LADAR) architecture developed at Sandia National Labs. The instrument acquires hyperspectral data in a single snapshot and spatial data in a series of snapshots. The system has 29 spectral bands, 1024 range samples, and approximately 80 x 80 spatial sampling. The RIS is discussed along with analysis of test data.
The development of an imaging spectrometer to acquire 3 spatial dimensions and hyper-spectral information simultaneously is detailed. The spectrometer is based on the Computed Tomographic Imaging Spectrometer (CTIS) developed at the Optical Science Center and the Scannerless Laser Radar (LADAR) architecture developed at Sandia National Labs. The new 4-D imager, called the Spectral LADAR System (SLS), operates in the visible to near-infrared portion of the spectrum (600-900 nm). The system has 30 spectral intervals (10 nm bands), 1024 range samples, and approximately 80 x 80 spatial sampling. CTIS and LADAR are discussed, as well as preliminary results of the SLS.
