Calculated inner electric field distribution in CdxZn1-xTe detector can be better applied in fields such as solar cells, infrared and ultraviolet detection, and the carrier density, space charge. The internal distribution of the electric field played an important role in the CdxZn1-xTe planar detectors. Understanding the detection characteristics of CdxZn1-xTe under ultra-high X-ray flux. Ultimate outcome explanation when the roentgen ray flux is particularly above the average, there will be severe space charge accumulation and internal electric field distortion. This may seriously affect the performance of the detector.
For industrial CT, the existing 3D measurement method based on industrial CT sequence imaging needs to be improved in terms of accuracy, speed and the degree of automation. In this context, based on the existing imaging measurement theory and taking the industrial CT sequence imaging as the experimental object, two volume measurement methods have been proposed this paper based on the industrial CT sequence imaging. This method was applied to carry out equal spacing stratified CT scan on three typical shapes of standard steel workpiece and Actual workpiece with inner cavity, and the obtained sequence fault imaging was measured and analyzed and verified. The experimental results show that the two measurement methods proposed in this paper improve the accuracy of measurement by two to three orders of magnitude and the accuracy of measurement is better than 1% compared with the existing volume measurement algorithm, which can meet the high precision requirements of the engineering application.
