CCDs (Charge-Coupled Devices) have high sensitivity and low noise characteristics that offer significant ad- vantages for diverse scientific detection applications. However, CCD imaging systems are susceptible to both intrinsic and extrinsic interference due to multiple charge transfers during the readout process. The CCD used in the AST3-II astronomical telescope located at Dome A in Antarctica has been severely affected by electromagnetic interference, resulting apparent stripes across the entire CCD images. To address this issue, we propose a novel correction method based on the Hough transform that effectively mitigates such interference effects. By applying the correction, we can significantly reduce such risks and enhance the reliability of exoplanet detection.
