Abstract

Based on the analysis of the present testing principal and methods, a novel testing design for the resolution of night vision instrument with faint light is presented. According to the principle technical design including the programmed resolution chart with adjustable pattern, Cathegreen collimator and CCD image sampler, this paper provides a unique testing equipment to the resolution of night vision instrument with faint light which can all be controlled, processed and displayed by computer. This testing equipment overcomes many defects of the traditional testing methods such as the harsh request of the testing field and environment, the inconvenience of changing the resolution chart and the influence of the subjective factor etc. Because of its small volume, light weight, high computerization and simple operation, the testing efficiency is improved greatly. Also, with its high accuracy and low cost, this research work can be reference to much more accuracy resolution testing of other optical instruments. It has a good prospect to be popularized and applied.
