Title (EN) SENSOR ARRAY IMAGING DEVICE
(FR) DISPOSITIF D'IMAGERIE À RÉSEAU DE CAPTEURS
Abstract:
(EN) A system produces sensed images. The system includes a sensor array, an image display device, and a processor that generates an image illustrating contents of an expanded field of view. The processor receives sensor element data from the sensor array, performs zero padding and discrete Fourier transform to result in a sensor wavenumber data buffer. The processor determines reference point locations, and generates a reference Fresnel field. The processor obtains an inverse Huygens- Fresnel transfer data buffer based on the reference Fresnel field. The processor multiplies each data element of the sensor wavenumber buffer with each corresponding data element of the inverse Huygens-Fresnel transfer data buffer. The processor generates a rectilinear spectrum data buffer based on the multiplication. The processor performs Stolt mapping and uniformly resampling to achieve image data.
(FR) L'invention concerne un système qui produit des images détectées. Le système comprend un réseau de capteurs, un dispositif d'affichage d'images et un processeur qui génère une image illustrant le contenu d'un champ de vision étendu. Le processeur reçoit des données d'éléments de capteurs en provenance du réseau de capteurs, effectue un remplissage par zéro et une transformée de Fourier discrète pour obtenir une mémoire tampon de données de nombres d'ondes de capteurs. Le processeur détermine des emplacements de points de référence, et génère un champ de Fresnel de référence. Le processeur obtient une mémoire tampon de données de transfert de Huygens-Fresnel inverse basée sur le champ de Fresnel de référence. Le processeur multiplie chaque élément de données de la mémoire tampon de nombres d'ondes de capteurs avec chaque élément de données correspondant de la mémoire tampon de données de transfert de Huygens-Fresnel inverse. Le processeur génère une mémoire tampon de données de spectre rectiligne basée sur la multiplication. Le processeur effectue un mappage de Stolt et un rééchantillonnage de manière uniforme pour obtenir des données d'image.
