Description
Technical field
The invention belongs to optical analog emulation and technical field of measurement and test, it is related to a kind of energy for infrared target simulator
Adjusting means.
Background technology
In infrared simulation system, infrared target simulator is used to provide an infrared target source, and all of test is all enclosed
Around the characteristic spread of infrared target simulator.Infrared target simulator is made up of target source and projection lens, and projection lens is by mesh
Mark source images project to infinite point.In l-G simulation test, it usually needs the energy to infrared target is adjusted, to target seeker
Tested under the conditions of different-energy, to study target seeker under different target distance, different weather state to the anti-of target
Should.Reflect the temperature characterisitic of target due to the temperature of black matrix, thus target energy decay should not be by changing blackbody temperature reality
It is existing.Conventional infrared energy regulation has two ways：One kind is that, by neutral filter, another kind is by polarization fading piece.
All there is certain limitation using upper in two kinds of methods of adjustment.The transmitance of neutral infrared attenuator typically becomes with wavelength, no
Broadband Uniform attenuation can be realized；And polarization fading piece is made up of two panels linear polarizer, near that a piece of polarization of infrared target
Piece absorbs 50% or so target energy, needs to carry out polarizer cooling ability normal work in higher-energy state.
The content of the invention
The present invention declined using neutral filter and polarization in existing infrared target simulator energy adjustment method to be overcome
Subtract that regulative mode that piece regulation energy is present is single and the problem that has certain limitations of tool, there is provided a kind of energy conditioner, can
For the infrared target simulator of transmission-type, reflective, binary channels and multi-channel coupling formula, for adjusting what is simulated in simulator
Target or the energy of interference, allow target seeker that target or the interference of different-energy are received in infrared simulation test experiments,
There is simple structural principle, strong applicability, be adapted to each wave band.
The purpose of the present invention is achieved through the following technical solutions：
A kind of energy conditioner for infrared target simulator, positioned at infrared target simulator high temperature blackbody front or illumination
In pipeline, it is made up of energy adjustment disk and motor, wherein：Described energy adjustment disk is circular sheet, on circular sheet
Averagely mark off several fan-shaped, each fan-shaped transmitance is different；Described motor is according to infrared simulation system emulation
Need, drive energy adjustment disk to rotate, switch different sector regions.
Compared with prior art, the present invention has the advantages that：
1st, structure and principle are simple, and production skilled worker is easy；
2nd, strong adaptability, is adapted to the infrared target simulator of various structures；
3rd, spectral region is wide, is adapted to the use of the infrared target simulator of each wave band.

Fig. 1 is position view of the energy conditioner in infrared target simulator；
Fig. 2 is energy conditioner structures schematic diagram.
Fig. 3 is energy energy adjustment disk 3-1 structural representations.
Specific embodiment
Technical scheme is further described below in conjunction with the accompanying drawings, but is not limited thereto, it is every to this
Inventive technique scheme is modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should be covered
In protection scope of the present invention.
As shown in Fig. 2 the energy conditioner 3 that the present invention is provided is made up of energy adjustment disk 3-1 and motor 3-2,
Energy adjustment disk 3-1 is circular metal plate, and averagely 8 sectors are separated on circular metal plate, is respectively designated as I-VIII, each fan
Shape transmitance is respectively 0%, 15%, 30%, 45%, 60%, 75%, 90%, 100%.
As shown in figure 1, energy conditioner of the invention 3 is located at the front of high temperature blackbody 5 of infrared target simulator or shines
In bright pipeline.The infrared target simulator is by optical coupling system 1, target diaphragm 2, energy conditioner 3, illumination optical system
System 4, high temperature blackbody 5 is constituted, and the infra-red radiation that high temperature blackbody 5 sends is collimated by lamp optical system 4 and projects to energy adjustment
Device 3, output energy size is adjusted by energy conditioner 3, and infra-red radiation is projected on target diaphragm 2, then by light
Learn the coupling of coupled system 1 output to target seeker entrance pupil.
When infrared target simulator is started working, motor 3-2 is according to infrared simulation system emulation needs, kinetic energy
Amount adjustment disk 3-1 is rotated, and switches different sector regions, changes the energy size of its transmission, so as to realize changing whole infrared imitative
True system output energy.
