Abstract
The present invention relates to a super visibility range telescope shooting method. A viewed object is observed in a super visibility range, and the near infrared invisible light of the measured object is picked up by a near infrared band pass light filter. A charge coupling imaging ship is used as a pickup element of a near infrared invisible light image and respectively enters an image processing device and a display device by a video generation circuit and a composite circuit. The present invention can be widely used for various occasions needing remote observation comprising the blindness complementing operation of a blind zone in radar monitoring. The present invention has a wide application range, and the limitation of a meteorological visibility range is broken through. An observation range of the present invention is 1.5 to 2 times of that of the prior art under the weather condition of poor visibility. Simultaneously, a viewed picture can be recorded in real time to be analyzed and processed.
