The miniaturized all-fiber photoacoustic spectrometer (FPAS) consists of a single optical fiber, a silica capillary, and an elastic membrane. The fiber's end facet and the membrane form a Fabry ...

This isn’t the first time I’ve written about MIT’s photoacoustic work. They’ve used it for spectroscopy that can detect gasses at a distance. Of course, if you are willing to allow a ...
