The present invention provides an economically feasible robust spatial heterodyne spectroscopy (SHS) interferometer. A first type prior art monolithic SHS interferometer is exceedingly expensive, whereas a second type of prior art SHS interferometer is extremely large and has many components, which need to be tuned. The present invention is much less expensive than the first type of prior art SHS interferometer and is much smaller that the second type of prior art SHS interferometer.
This Application claims the benefit of U.S. Provisional Application No. 60/740,295, filed Nov. 18, 2005, the entire disclosure of which is incorporated herein by reference.
