Abstract
A system for imaging an object, the system including: a detection zone; a first unit adapted to selectively emit radiation of at least one first wavelength and radiation of at least one second, different wavelength for at least partly illuminating the object in the detection zone; a second unit adapted to capture at least partial images of the illuminated object; and an aperture placed in an optical path between the detection zone and the second unit. The aperture includes: a first, central area adapted to transmit radiation of at least the first wavelength(s) and the second wavelength(s); and a second area surrounding said first area, which second area is adapted to block radiation of the second wavelength(s), but transmit radiation of the first wavelength(s). Also, an imaging method, and use of a diaphragm in a reverse vending machine.
