Abstract
A time-resolved hyper-spectral imaging system for imaging a sample, includes a radiation source suitable for illuminating the sample repeatably, a first optical system configured to form an image I of the sample on a spatial light modulator forming a transmission or reflection mask P, a processor connected to the spatial light modulator and configured to make the transmission or reflection mask P vary for each repetition of the illumination, a second optical system suitable for focusing the radiation transmitted or reflected by the spatial light modulator so as to form, in its image focal plane, a partial image S=P·I; the imaging system being wherein it comprises: a dispersive device comprising a slit placed in the image focal plane of the second optical system, the dispersive device being suitable for spatially splitting the various wavelengths of the radiation transmitted or reflected by the spatial light modulator; a streak camera arranged so as to be illuminated by the radiation issuing from the dispersive device and configured to acquire a plurality of time-resolved partial images of the sample, the images being associated with respective and different transmission or reflecti…
