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

摘要

The present application relates to a dual-energy detection method, a dual-energy detection system and a dual-energy detection device, which relate to the field of radiation detection. The apparatus includes: a first pixel detector array proximal to a radiation source, the detector array configured to detect radiation source photons having relatively low energy; and a second pixel detector array distal from the source of radiation, the detector arrangement having photons for detecting the source of radiation; which have relatively high energy, is configured; wherein the first pixel detector array includes a plurality of rows of first pixel detectors, the first pixel detector including a first sensitive medium, a first photosensitive device, a first incidence plane for incidence of the radiation source, and a first window coupled to the first photosensitive device wherein the first plane of incidence faces the radiation source; wherein the second pixel detector array includes a single row of second pixel detectors, the second pixel detector including a second sensitive medium, a second photosensitive device, a second incident plane, and a second window coupled to the second photosensitive device; and wherein each of the second pixel detectors has 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 capability and improves the effective detection of rays.
