AbstractVescent Photonics determined the feasibility of a miniaturized, robust, Fourier transform spectrometer (FTS) for either in-situ or remote chemical and spectral analysis. During this phase I effort we investigated innovative, optical waveguide technology, capable of providing an unprecedented, entirely electro-optic replacement for millimeter or even centimeter scale mechanical mirror translation. This technology, developed by Vescent Photonics, enables a fully integrated FTS chemical sensor unit. The attributes of this sensor: i) small size, comparable to a book of matches, ii) low mass, only tens of grams, iii) small energy consumption, < 10-3 Watt-hours per measurement, iv) high sensitivity, detectable chemical densities < 1013 per cm3, and v) robust monolithic construction, are aptly suited for future NASA missions. Such a sensor can be integrated and deployed with a variety of exploration platforms. A single device will provide identification and quantification of multiple compounds (e.g., biogenically important CH4, NOx, NH3, H2O, and many more).
