NRL

Micro-spectral sensors and methods are presented in which a Fizeau wedge interference filter is disposed between a focal plane array and a visible scene with an increasing wedge filter dimension varying along a scan direction, where the scene is scanned along the FPA to obtain light intensity measurements of a given scene location at different times using different FPA sensor elements through different wedge filter thicknesses, and the measurements correlated to the given scene location are Fourier transform to generate spectral data for the location.
