2. Dr. Lin Ma receives two grants from the US Air Force SBIR program to research and develop Hyperspectral Tomography Sensors.  In this research, we creatively use hyperspectral absorption spectroscopy to significantly reduce the number of projections required for satisfactory tomographic imaging.  Therefore, the implementation difficulty can be drastically reduced and performance improved.  The figure below illustrates the concept.  The technique, named hyperspectral tomography, uses advanced lasers to scan absorption spectra at rapid rate at multiple locations.  Novel inversion algorithms then retrieve critical flow information (e.g., temperature, and concentration of chemical species) from the measured spectra with both spatial and temporal resolution.
