Abstract
An image acquisition system comprises: a single set of focussing optics focussing an incident beam from a scene to be imaged on a first sensor and a second sensor exhibiting identical spectral response curves; followed by separation means separating the irradiance of the beam coming from the focussing optics into first and second predetermined fractions, the separation means orienting the first fraction towards the first sensor and the second fraction towards the second sensor; control means for controlling a first acquisition time of the scene to be imaged by the first sensor to obtain a first image and/or a second acquisition time of the scene to be imaged by the second sensor to obtain a second image; and merging means that merge the first image coming from the first sensor and the second image coming from the second sensor to generate a final image.
