Abstract
A concept of Fourier-transform infrared spectrometer integrated on a focal plane array (FTIR-FPA) has been developed for very fast acquisition of spectral signatures. The basic idea is to use the upper surface of the focal plane array as the first mirror of a two-wave interferometer, which creates interference fringes directly inside the active layer. Two technologies have been developed. In a "monolithic" version of our FTIR-FPA concept, the cavity is made by grinding the substrate to the shape of a wedge. In a "hybrid" version, the cavity is made by hybridizing a Silicon plate just above the focal plane array.
