An Improved Design Method Research on PDT

To improve the detection performance of photoelectric detection target (PDT), the technology of defocuses was applied in detection optics system to eliminate photoelectric detector detection blind area, and the method of automatically adjust benchmark voltage was used to meet the different illumination condition measure. Analyze the improved method and design principle on PDT, study the detection circuit and automatically adjust benchmark voltage circuit, design optics detection structure and slit diaphragm. According to the principle, the detection distance on PDT was analyzed. Through experimentation in shooting range, it proves that the improved design method can satisfy current test demand and improve detection performance in PDT. Now, the new PDT has been applied successfully in shooting range and gain good achievement.
