Theses and Dissertations
Our group recently developed a new type of Fourier transform Raman spectrometer, the spatial heterodyne Raman spectrometer (SHRS), for planetary exploration. The SHRS is a high spectral resolution, high throughput, compact dispersive interferometer, similar in design to a Michelson interferometer, where the mirrors are replaced by stationary diffraction gratings. The SHRS has no moving parts and does not require an entrance slit, making the throughput of the system orders of magnitude larger than a typical dispersive spectrometer. The wide field-of-view (FOV) of the SHRS enables wide area measurements without loss of sensitivity or spectral resolution and offers advantages such as …

Space exploration is arguably one of the most important endeavors our species has ever undertaken. Rapid advances in rocketry and robotics in recent years has allowed for positioning of complex scientific instruments on other planets with a precision that was previously thought impossible. This, along with the need for more sophisticated chemical measurements to achieve the goals of new, more ambitious missions and recent advances in in-situ and remote spectroscopic techniques, has led to a boom in the use of spectroscopic instruments for space exploration. However, future missions to the moons of Jupiter and Saturn, along with other planetary bodies …
