In order to improve the accuracy of discharge detection of a domestic ultraviolet (UV) imager, the relationship between the photon number and the discharge magnitude was established. In this paper, the rod-plate gap model was selected as the research object. By using the domestic ZT301 UV imager, the characteristics of photon number and discharge magnitude varied with voltage intensity, observation distances and instrument gains were studied. Experimental results show that the photon number and the discharge magnitude are nonlinear increased with the increasing of voltage. By changing the observation distance and gain, fitting curves of the photon number and the discharge magnitude were obtained, which still satisfied the nonlinear increasing relationship. The research results lay a foundation for practical engineering applications of the domestic UV imager.
