With the continuous development of ultraviolet technology, the working band of UV detector is more controllable and optional, and the sensitivity has been greatly improved, so it has been widely used in ultraviolet camera, flame detection, welding detection and other fields with its unique advantages, it is of great significance to study the performance of ultraviolet detector parts. In this paper, we designed a set of evaluation and testing devices for detecting the signal-to-noise ratio, resolution, dynamic range and other parameters of ultraviolet ICCD (intensified charge-coupled device) detector after carrying out theoretical evaluation of ultraviolet detection and imaging photoelectric system and studying its related testing technology. In this paper, firstly we analysed the definition and the testing principle of the ultraviolet ICCD detector’s relevant parameters, such as signal-to-noise ratio, resolution, dynamic range, and designed the relevant algorithm model on the basis of that, then designed the supporting related hardware such as: Uniform light source system, test target, dark box, video processing acquisition system, etc. Secondly, based on LabVIEW platform, the software of related data acquisition and analysis is developed, and the video real-time display is realized, and finally the test experiment of signal-to-noise ratio, resolution and dynamic range is carried out to evaluate the performance of UV ICCD detector.
