The Design Of A Laser Threat Warning Device

The principles of laser technology, photo-electronic transformation technology and photo-electronic signal gathering technology were discussed in this paper, A new imaging laser threat warning device used in antagonizing laser-guiding weapon was designed and its main parts and circuit were described in detail. Some advanced methods such as frame storage and subtraction technology and new devices such as CCD and wide-angle far-center fish-eye lens were used. The characters of this device were high sensitivity, wide-angle warning resign, accurate azimuth angle of the coming laser and low wrong-warning rate.
