description A multi-spectral light-field device, including an imaging component, arranged to image a light-field emitted by an object point of an object and for setting an input signal including a range of incidence angles on an optical filter. The optical filter has a transmission function depending on the incidence angles to transform the input signal into an output signal including a spectral distribution associated to an angular distribution. A micro-lens array is arranged to transform the spectral distribution of the output signal into a spatial distribution on an image plane. This multi-spectral light-field device is adapted to be integrated in a small, compact and/or handheld device, as a smartphone and also to deliver high resolution images. Also an imaging system which is a compact twin camera device. Also an object identification system allowing an image reconstruction in real-time on limited computational resources of a mobile device, by using a machine-learning module.
