Abstract:
1. A stationary Fourier transform spectrometer comprising a substantially transparent substrate having a first face and a second face; semiconductor photosensitive elements having active faces coinciding with an image plane; said substrate being integrated against said photosensitive elements to form a single component, said first face of said substrate being planar and coinciding with the image plane on said photosensitive elements and forming with said photosensitive elements a substantially non-reflecting diopter, said second face of said substrate carrying a semi-reflecting diopter so as to form a two-wave stationary interferometer between said first face and second face, the thickness between said first face and second face of said substrate being substantially constant in front of each photosensitive element and varying regularly from one photosensitive element to another.
