Title
(EN) A METHOD AND SYSTEM FOR DETECTION OF ELECTROMAGNETIC RADIATION
(FR) PROCÉDÉ ET SYSTÈME DE DÉTECTION D'UN RAYONNEMENT ÉLECTROMAGNÉTIQUE
Abstract
(EN)
The invention relates to a device and method for imaging electromagnetic radiation from an object. The device includes entrance optics for allowing the electromagnetic radiation to enter the device, including an image plane onto which an image of the object is to be imaged. The device includes an interferometer having a measurement arm, wherein the image plane is in the measurement arm. The device includes a transformation layer, at the image plane, for transforming the electromagnetic radiation into a spatiotemporal variation of the refractive index of the transformation layer for causing spatiotemporal optical phase differences in the measurement arm of the interferometer that are processed to result in a representative image of the object.

L'invention concerne un dispositif et un procédé d'imagerie d'un rayonnement électromagnétique en provenance d'un objet. Le dispositif comprend une optique d'entrée pour permettre au rayonnement électromagnétique d'entrer dans le dispositif, comprenant un plan d'image sur lequel doit être formée une image de l'objet. Le dispositif comprend un interféromètre doté d'un bras de mesure, le plan d'image se trouvant dans le bras de mesure. Le dispositif comprend une couche de transformation, au niveau du plan d'image, destinée à transformer le rayonnement électromagnétique en une variation spatiotemporelle de l'indice de réfraction de la couche de transformation pour provoquer des différences de phase optique spatiotemporelles dans le bras de mesure de l'interféromètre qui sont traitées en vue de produire une image représentative de l'objet.
