Technical field
The invention belongs to the analog light source field of measuring technique, relate to the centering distant object and carry out analog detection through laser and infrared light.
Background technology
The two waveband target simulator is to be used for that thereby the debug tracing device realize to be caught and the high accurancy and precision professional equipment of tracking target; Remedied in the traditional detection precision and to have adopted real huge the expending of penetrating experiment and producing, played crucial effect for the research that the precision of seeker improves.The target simulator of the single wave band that adopts at present, emulation degree all receive the effect that influence that aspects technology such as energy simulation precision and scope limit to is difficult to reach high emulation, have not caught up with the paces of high speed development guidance technology at simulation context and simulation precision.
The technology of modern development can only be accomplished the simulate effect of single wave band; Simulation process for the target medium and long distance is easy is imperfect; Especially the effect for laser analog be not very desirable aspect precision adjusting and the continuity, so native system satisfies high accuracy, wide region, continuous complete object simulation process of regulating.
Summary of the invention
The objective of the invention is to overcome the energy simulation that single wave band carries out in the target simulator in the past and the not high defective of bringing of fidelity; The design of a kind of brand-new laser and the common simulated target of infrared double-waveband has been proposed; Target is carried out the emulation of high accuracy, wide region through the light of two kinds of different-wavebands; The present invention can be real-time the change procedure of continuous adjusting energy; Advantage such as volume is little, precision is high, simple in structure and cost is relatively low can satisfy the simulation for the target energy variation characteristic in actual use fully.
Technical scheme of the present invention is: the present invention provides a kind of two waveband target simulator, is made up of Master Control Unit (1), infrared energy analogue unit (2), laser emission element (3), laser energy analogue unit (4), 3-5 μ m infrared simulation unit (5), emergent ray (6), two waveband optical projection system (7), optical fiber (8), cable (9).
Simulator is simulated the energy variation of 1.064 μ m laser and 3-5 μ m infrared double-waveband; Infrared light is sent by infrared energy analogue unit (2); Form the adjustable infrared light of energy of system requirements wave band through 3-5 μ m infrared simulation unit (5); Laser is sent by laser emission element (3); Get into laser energy analogue unit (4) through laser emission element (3) and obtain 1.064 adjustable μ m laser of energy, form emergent ray (6), close light by two waveband optical projection system (7) completion again and make directional light penetrate through the unified control of Master Control Unit (1).
Above-mentioned infrared energy analogue unit (2) by TO-8 as 3-5 μ m infrared light supply; Good ejaculation and veiling glare that TO-8 type infrared light supply can be accomplished 3-5 μ m infrared light are few; Because system is low to requiring of regulating of infrared energy, promptly is made up of simple stable voltage variable power circuit.
Above-mentioned laser emission element (3) adopts no water-cooled, high efficiency, high-peak power DPL as 1.064 μ m LASER Light Sources, meets the requirement of system to this wave band of laser fully.
Above-mentioned laser energy transmitter unit (4) adopts the method for wide region, the continuous mechanical light modulation of high accuracy to carry out the adjusting of laser energy, forms (like Fig. 2) by fixed station (11), translation stage A (12), wedge A (13), translation stage B (14), wedge B (15).Translation stage A (12) and translation stage B (14) keep symmetry and can go up to accomplish at fixed station (11) moving horizontally, and wedge A (13) and wedge B (15) are by AB
2Material is processed, and the shape size is in full accord, and is in long right-angle side and is placed in parallel on the translation stage.
Horizontal relative motion through wedge A (13) and wedge B (15) makes laser change through the distance of two wedges, and attenuation degree changes simultaneously, to realize continuously adjustable requirement.
Above-mentioned two waveband optical projection system (7) is by (like Fig. 3) CaF
