Multimodal optical spectrometers for remote chemical detection

摘要

We have developed a class of aperture coding schemes for Remote Raman Spectrometers (RRS) that remove the traditional trade-off between throughput and spectral resolution. As a result, the size of the remote interrogation region can be driven by operational, rather than optical considerations. We present theoretical arguments on the performance of these codes and present data from where we have utilized these codes in other spectroscopy efforts.
