在此，我们报告了商用单片有源像素传感器（MAPS）相机在强剂量率照射下的γ射线电离辐射响应，以及强辐射条件的在线检测和监测系统。我们首先给出了三种类型的 MAPS 相机的分布结果，并在强剂量率范围内建立了平均响应信号与辐射剂量率之间的线性关系。当摄像头模组参数设置为自动时，视频帧中有明显的响应信号，但线性响应很差。然而，固定的图像参数不能很好地适应环境的变化，影响视频帧的质量。制作了双模块在线辐射检测监测探头，可同时进行有效的视频监测和辐射检测。测量结果表明，剂量率在60~425 Gy/h范围内，剂量率检测误差小于5%，可见光图像没有因辐射响应事件和辐射损伤的干扰而出现明显的畸变、变形或色偏。因此，系统测试结果表明，该系统可用于强辐射环境下的在线检测和监测。
Herein, we report the γ-ray ionizing radiation response of a commercial monolithic active-pixel sensor (MAPS) camera under strong-dose-rate irradiation with an online detection and monitoring system for strong radiation conditions. We present the first results of the distribution of three types of MAPS camera and establish a linear relationship between the average response signal and radiation dose rate in the strong-dose-rate range. There is an obvious response signal in the video frames when the camera module parameters are set to automatic, but the linear response is very poor. However, the fixed image parameters are not good at adapting to the changes of the environment and affect the quality of the video frames. A dual module online radiation detection and monitoring probe was made to carry out effective video monitoring and radiation detection at the same time. The measurement results show that the dose rate detection error is less than 5% with a dose rate in the range of 60 to 425 Gy/h, and the visible light image does not have obvious distortion, deformation, or color shift due to the interference of the radiation response event and radiation damage. Hence, the system test results show that it can be used for online detection and monitoring in a strong radiation environment.
