A standing wave spectrometer is turned into a wavelength tunable band-pass filter by the addition of a reflective coating.
It results in the standing wave filter (SWF), a miniaturized Fabry-Perot band-pass filter with a semi-transparent detector
that can be constructed into a pixel-tunable focal plane array, suitable for hyperspectral imaging applications. The
asymmetric Fabry-Perot cavity is formed between the reflective coating and a tunable mirror, originally part of the
spectrometer. The predicted performance of the SWF is optimized through modeling based on the matrix formalism used
in thin film optics and with FDTD simulations. The SWF concept is taken from an ideal device to a focal plane array
design that was fabricated with 40 micron pixels using semi-conductor processing technology. First-light spectra
measured from the 100 pixel Standing Wave Filter array agree with predictions and prove the concept.
