The effective distance of photoelectric imaging system can be improved obviouslv under the conditions of low visibility through the near-infrared high-pass filtering and digital image processing echnology,but the near-infrared high-pass filtering increase the minimum operating illumination of the system.The paper has made research on the conversion of the minimum illumination in the beyond visual range photoelectric imaglng system,and worked out the calculation of the minimum operating illumination under the condition of the actual optical system in the F-number and near-infrared high-pass filter. The paper plays a theory instructed role in the design and analysis of photoelectrical imaging system.
