Abstract:
1. A micro-machined optical measuring device comprising: a set of photosensitive detector elements situated on a first face of a first support, the photosensitive elements belonging to an imager; and a second support, assembled to the first support, the second support including a first face through which radiation can penetrate and a second face positioned between the first face of the first support and the first face of the second support, the second face forming a non-zero angle θ with the first face of the second support and a non-zero angle α with the first face of the first support; the second face being semi-reflective, the first support and the second support being positioned such that an interferometric cavity is made between the second face and the photosensitive detector elements, the interferometer cavity being a space delimited by a surface of the photosensitive elements and the semi-reflective face of the second support, positions of the first face of the first support and the second face of the second support being constant over time so as to form a static interferometric cavity, the device being an interferometric device of static interferometer type with two waves having at least partially a same spectral content.
