摘　　要：介绍了一种便携式电晕放电检测紫外相机的设计方案。该相机选用320×256元AlGaN基"日盲"紫外焦平面作为探测芯片,其波长范围为240～280 nm,具有可见光和紫外两个通道,充满电后能持续工作6 h以上。实验结果表明,该相机可以成功获取清晰的紫外目标图像,并可实现对紫外信号的实时监测。A portable UV camera for corona detection is presented. The camera uses a 320×256 pixcl solar-blind UV FPA with the spectral range from 240 to 280 nm as its core detector. It has both a visible channel and a UV channel and can continuously operate for six hours after it is fully charged. The experimental results show that the camera can acquire clear UV images of the targets successfully and can be used to monitor UV signals in real time.
