The image enhancer expands the effective utilization of low-light-level electron, reduces the escape probability of emergent electron at the photocathode in a magnetic mirror, more effectively accumulates optoelectronic signals at normal temperature and achievesthe enhancement to extremely weak light signals, thus achieving clear imaging at the illumination intensity of 10<-8>lx.

The invention provides an anti-electromagnetic-interference anti-unmanned-aerial-vehicle catching device comprising a head, a tail, a small wing and a propeller structure. A catching device control system is arranged in the head and comprises an information collection module, a control unit and a propeller motor. The information collection module comprises an image collection module, a laser radarscanning module and a close-range electromagnetic wave detection module. The image collection module, the laser radar scanning module and the close-range electromagnetic wave detection module are connected with the control unit. The propeller motor is connected with the propeller structure. The tail is arranged behind the head and is internally provided with a catching net. The small wing is arranged at the head and is connected with the control unit. A compensating circuit is further arranged in the catching device and can conduct opposite offsetting with electromagnetic wave, received by the close-range electromagnetic wave detection module, of the propeller motor of the catching device. The anti-electromagnetic-interference anti-unmanned-aerial-vehicle catching device can catch an unmanned aerial vehicle accurately, thus the escape possibility of the target unmanned aerial vehicle is low, interference is smaller, and catching is more accurate.
