摘要： The invention relates to a device for discriminating Cerenkov and scintillation radiation and a beam inspection device, comprising an inspection head comprising a scintillator (13) and at least one ionizing radiation diffuser block (15a, 15b), a device (1) for discriminating Cerenkov and scintillation radiation, and an imaging system (17) for forming an image from at least a part of the inspection head. The invention furthermore relates to a corresponding method. In order to suppress spurious Cerenkov radiation contributions to the scintillation radiation the device comprises periodically arranged first and second filters (3, 5), having different relative absorption properties with respect to scintillation radiation and ionizing radiation. The invention also relates to an imaging apparatus comprising means for reducing parasitic contributions to a signal of interest, wherein the apparatus comprises a modulation mask for modulating a signal of interest, wherein, in particular, the signal of interest is the signal illuminating the object or the signal emitted or reflected from the object, and an image analyzing means configured to remove - at least partially - parasitic contributions added to the modulated signal of interest based on the shift of the signal of interest towards higher frequencies due to the modulation.
