The laser spot image quality is one of the important index of laser guided weapons. In order to check the index, the advantages and disadvantages of general laser spot testing technology were analyzed. According to the several factors affecting the test precision field of laser spot, a testing system of high accuracy laser spot outfield detection based on the double CCD with the indirect method of non-contact type was designed. The system had various functions like recording the spot and image processing, realtime monitoring, calculation of laser coding and error value, spatial variation of energy density foward lens and the laser pulse leakage rate and other functions. It also had characteristics of testing large dynamic range, high resolution, anti external interference was strong, easy to use etc. It can do the test and analysis of laser facula evaluating field with high precision. The test system can solve the problems in the field of laser spot test through the test analysis and application of the external field,it have played an important role in the process of the field test outdoor.
