Dual-energy detection device, dual-energy detection system and dual-energy detection method

The present application relates to a dual-energy detection method, a dual-energy detection system and a dual-energy detection apparatus relating to the field of radiation detection. The apparatus includes: a first pixel detector array proximal to a radiation source, the detector array for detecting radiation source photons have relatively low energy, configured; and a second Pixeodetektoranordnung distally from the radiation source, the detector array for detecting the radiation source photons; the relatively high energy possess is configured; wherein the first pixel detector array includes a plurality of rows of first pixel detectors, wherein the first pixel detector includes a first photosensitive medium, a first photosensitive device, a first incident plane for the incidence of the radiation source and a first window, which is coupled to the first photosensitive device, wherein the first incidence plane of the radiation source facing; wherein the second pixel detector assembly comprises a single row of the second pixel detectors, wherein the second pixel detector includes a second photosensitive medium, a second photosensitive device, a second plane of incidence and a second window, which is coupled to the second photosensitive device; and wherein each of the second pixel detectors having the same pixel area as a corresponding plurality of first pixel detectors thereof. The present disclosure implements an identification of the effective atomic number of objects, improves the space identification ability, and improves the effective detection of beams.
