Effectiveness Analysis and Characteristic Parameters Characterization of Night Vision System under the Twilight Aids
摘要
Abstract
In order to properly evaluate the performance and efficacy of low light level(LLL) night vision systems, the visual range detecting equation and twilight aids effectiveness of LLL night vision system are analysed systematically. The results show that the “twilight aids can improve observation distance several times”should not be a technical indicator to determine the twilight aids effectiveness. The four characteristic parameters(Em、Ex、Ey、Eb) of twilight aids effectiveness are defined and characterized respectively. The target range experiment results show that LLL night vision system could not obtain a clear image of the scene when the environmental illuminance is 0.6×10-3 lx and the LLL night vision system can work normally under twilight aids applying characteristic parameter Ex. The four characteristic parameters of twilight aids effectiveness have the important guiding significance to research twilight aids technique.关键词
