ABSTRACT:
An arrangement for the multispectral imaging of objects, preferably targets, including an optical system for imaging the object dots of the objects on at least one charge-coupled semiconductor element, with each charge-coupled semiconductor element including a plurality of light sensitive individual detectors and a charge-transfer circuit arrangement connected to said detectors. The plurality of individual detectors includes at least two groups of detectors with each group being sensitive to light energy of a different wavelength or wavelength range. The groups of detectors are disposed on the surface of the semiconductor element such that the optical system, due to its scatter circle, images each object dot on at least one detector of each group, and the output signals of each individual detectors are fed to the charge-transfer circuit arrangement of the semiconductor element.
