Mechanism of Total Ionizing Dose Effects of CMOS Image Sensors on Camera Resolution

The nuclear industry and other high-radiation environments often need remote monitoring equipment with advanced cameras to achieve precise control operations. CMOS image sensors, as a critical component of these cameras, get exposed γ-ray irradiation while operating in such environments, which causes performance degradation that adversely affects camera resolution. This study conducted total ionizing dose experiments on sensors systems thoroughly analyzed the impact mechanisms dark current, Full Well Capacity, quantum efficiency A quantitative evaluation formula was established evaluate Capacity sensor provides theoretical basis for radiation resistance strong development radiation-resistant cameras.
