Embodiment
[0071] (1) Design an optical system that meets the conditions through ZEMAX, the optical path diagram is shown in (a), and the spot diagram is shown in (b);
[0072] (2) Assemble the optical system designed in step 1 with the four-quadrant detector and the primary amplifier circuit board to construct a single detection channel, as shown in Figure (c);
[0073] (3) Based on the fact that the field of view of the single optical system in step 1 is 30°, it can be known by overcoming the blind zone analysis that 24 detection channels in step 2 are required to form the system as shown in figure (d), and the 24 channels are evenly arranged on a straight line 1 to 12, the diameter of the whole system is 460mm;
[0074] (4) On the basis of the overall system in step 3, design the human-computer interaction platform including: LCD display, power switch, buzzer and buttons.
[0075] The laser warning system designed by the method of the present invention can detect in all directions wi...

The invention discloses a construction method for an omni-directional laser warning system. The construction method for the omni-directional laser warning system comprises the following steps that first, an optical system is constructed to enable that the diameter of a light spot of laser imaging on a detector through the optical system is equal to the radius of a photosensitive surface so that the omni-directional laser warning system can detect a wider linear range and fully utilize energy of the light spot on photosensitive surface, and secondly, distortion is small when the light spot reaches the edge of the detector; then a single channel is constructed so that a laser in a certain azimuth range can be detected, the optical system, an optical filter, a four-quadrant detector and a first-level amplification circuit are integrated, and the advantages of miniaturization and high anti-jamming capability are achieved; and then the whole omni-directional laser warning system is constructed and is composed of 24 channels, and omni-directional 360 degrees detection without a blind area is achieved; and finally, a man-machine interaction platform is constructed so that high-precision positioning information can be displayed in real time, and working performance and operability of the omni-directional laser warning system are improved. According to the construction method for the omni-directional laser warning system, omni-directional laser warning can be realized, and good application prospects are achieved.
Description
technical field [0001] The invention relates to the field of laser warning systems, in particular to a method for constructing an all-round laser warning system. Background technique [0002] Since the appearance of laser in 1960, laser technology has developed rapidly and has been widely used in military affairs. Laser ranging, laser guidance, laser reconnaissance, laser fuze, laser aiming, laser tracking, laser target designation and other weapons and equipment have greatly improved the combat performance of the weapon system. The laser rangefinder has greatly improved the first hit rate of the artillery, and the laser-guided bombs, shells or missiles of laser-guided weapons can achieve precise strikes on specific targets. In the Gulf War, the Kosovo War and several other local conflicts, every important military effectiveness. The tactical and strategic high-energy laser weapon that is currently being developed rapidly has become a leader among new concept weapons with ...
