Abstract: The present disclosure provides a dual-energy detection apparatus and method. The dual-energy detection apparatus includes an X-ray source configured to send a first X-ray beam to an object to be measured; a scintillation detector configured to work in an integration mode, and receive a second X-ray beam penetrating through the object to be measured to generate a first electrical signal; a Cherenkov detector configured to be located behind the scintillation detector, work in a counting mode, and receive a third X-ray beam penetrating through the scintillation detector to generate a second electrical signal; and a processor configured to output image, thickness and material information of the object to be measured according to the first electrical signal and the second electrical signal. The dual-energy detection method provided by the present disclosure may acquire an image of the object to be measured that is clearer and contains more information.
