Active hyperspectral imager using a tunable supercontinuum light source based on a MEMS Fabry-Perot interferometer

We have developed an active hyperspectral imager based on a tunable near-infrared supercontinuum light source. Non-dispersive wavelength selection of the supercontinuum laser source is achieved with a microelectromechanical Fabry-Perot interferometer. The tunable light source enables the use of any monochromatic imaging sensor with a suitable spectral sensitivity for hyperspectral imaging. The imager is characterized and demonstrated in the laboratory for remote detection of ice.
