Title:
BACKSCATTER DETECTION MODULE
Document Type and Number:
WIPO Patent Application WO/2018/233456
Kind Code:
A1
Abstract:
A backscatter detection module, comprising a plate-like light-transmitting carrier, two layers of scintillators, and a light sensor. The light-transmitting carrier is made of a material that allows fluorescence photons to pass through, and has two light-transmitting planes opposite to each other and at least one light emergent end surface; the light emergent end surface is located between the two light-transmitting planes; the two layers of scintillators are respectively fixedly attached to the two light-transmitting planes; the light sensor is coupled to the light emergent end surface. By using two layers of scintillators and a light-transmitting carrier to absorb X-rays, the backscatter detection module greatly improves the detection efficiency. According to the detection module, the light-transmitting carrier is used as a light guide material, a light sensor is provided on the end surface, and the light-transmitting carrier can both transmit fluorescence photons and change the light path; thus, the thickness of a backscatter detector is greatly reduced.
