Photographic film or microscopic objects are transilluminated with a rotating angular light flux of a high aperture ratio. This enables retrieving information with a higher spatial bandwidth than heretofore possible. Furthermore, this way of transilluminating reduces, both, image noise and aliasing at the sensor array. The fundamentally different way of extracting information provides an improved basis for digital restoration of photographic material.In microscopic applications scattering or fluorescent details can be better separated from transmitted image content.
