Embodiment Construction
[0037] The technical content of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0038] like image 3 As shown, the X-ray sector drift detector provided by the present invention includes a digital signal processing module 8 and two detection modules, each of which is connected to the digital signal processing module 8 respectively. The detection module is used to receive X-ray fan irradiation, generate an electrical signal analog quantity proportional to the X-ray intensity, and output signal digital quantity after signal amplification and analog-to-digital conversion processing; the digital signal processing module 8 is used to The difference between the digital signals output by the two detection modules is used to calculate the output value of the X-ray sector drift detector.
[0039] In the embodiment of the present invention, the centerlines of the two detection modules in the width di...
