A spectral imager, including: a photodetector including a plurality of photosensitive sites exposed on a photosensitive surface; a collimating lens including an intermediate focal plane; an array of interferometers including two main waves, each including a cavity defined by two faces; an array of microlenses arranged in a plane parallel to the photosensitive surface, each microlens paired with an interferometer to form an optical pair, including an image focal plane coinciding with the photosensitive surface and facing a section of the photosensitive surface.

Fourier transform multi-channel spectral imager

The invention relates to a spectrograph () comprising a waveguide () provided with accesses (), a means for injecting two guided contra-propagative waves by each accesses in such a way that a spatial interference is formed in the waveguide, means () for detecting the energy of the evanescent wave of the guided field produced by the interference of said contra-propagative waves.

Contra-propagative wave spectograph

An interferential spectroscopy detector including a waveguide having an input side and a mirror on an opposite side, and means for detecting electromagnetic rays delivering an electric signal as a function of local intensity of an electromagnetic wave, detection being produced between an input side and the mirror.
