Description
Technical field
The present invention, for extraterrestrial target range finding and wireless laser communication compound, relates to laser communication and technical field of distance measurement.
Background technology
For extraterrestrial target, and distance and the communication function between main website is usually the big primary demand of system two.Range finding at present adopts two set autonomous devices to complete with communicating with being substantially, for the restricted occasion of steric requirements, autonomous device is more many, and required volume, weight, power consumption and system complexity are more big, and therefore Study of Laser communication and range finding complex technique are following a kind of development trends.Space laser range finding is divided into noncooperative target laser ranging and cooperative target laser ranging two kinds.The principle of noncooperative target range finding is that the laser beam (continuous or pulse) that range finder using laser sends is irradiated on testee, utilizes the diffusing characteristic diffuser of object, and range finder receives the laser signal that object diffuse-reflectance is returned, and realizes range finding by calculating the two-way time of laser.Cooperative target laser ranging adopts corner reflector as cooperative target, is arranged on testee by corner reflector, utilizes corner reflector by the characteristic of incident ray backtracking, it is achieved range measurement.Cooperative target laser ranging has, compared with noncooperative target laser ranging, the advantage that range accuracy is higher, measurement scope is farther, is first-selection remote, precision distance measurement.FSO is to adopt light as carrier wave, carries out the technology of the information transmission such as language, data, image in space.Owing to optical wavelength is short, therefore wireless laser communication has: traffic rate is high, message capacity is big, anti-interference, Anti TBIgG ability is strong, safe and secret, the advantages such as system bulk is little, lightweight, low in energy consumption, it is the important model of following two-forty, wide-band-message transmission, is one of most potential communication pattern.The present invention is directed to the feature of laser ranging and laser communication, it is proposed to a kind of set composite, it is achieved range finding and communicating integral.
Summary of the invention
Range finding communication integrated device based on modulation Reflex Reflector, it is characterised in that: this device includes inquiry optical sender 1, photoreceiver 2, manipulator 3, corner reflector 4 and two-dimension adjustment platform 5；Inquiry optical sender 1, photoreceiver 2 and two-dimension adjustment platform 5 are arranged on A end, inquiry optical sender 1 and photoreceiver 2 are arranged on two-dimension adjustment platform 5, inquiry optical sender 1 is parallel with photoreceiver 2, and during installation, boresight direction is orthogonal with the azimuth axis of two-dimension adjustment platform 5 and pitch axis three axle；Manipulator 3 and corner reflector 4 are arranged on B end, and manipulator 3 is fixedly mounted on the front end of corner reflector 4；
Inquiry optical sender 1 and photoreceiver 2 constitute transmitting and the reception of inquiry light；Two-dimension adjustment platform 5 realizes the alignment to B end target and tracking；Manipulator 3 and reflector 4 realize luminous reflectance and the function of information coding；
This device includes two kinds of mode of operations:
During range finding mode of operation, inquiry optical sender 1 launch inquiry light encoded after, it is irradiated on manipulator 3, manipulator 3 is opening state, incident illumination is not modulated, and light is by arriving corner reflector 4 after manipulator 3, owing to corner reflector 4 has the characteristic of incident illumination backtracking, therefore inquiry light is after corner reflector 4 reflects, and again by manipulator 3, returns to photoreceiver 2 according to original incident direction；Photoreceiver 2, by measuring transmitting and the interval Δ t of the time of reception of coding inquiry light, according to 2*d=c* Δ t, obtains the distance d of A, B 2, and wherein, c is the light velocity；
During communication operation mode, the inquiry light that inquiry optical sender 1 is launched, it is irradiated on manipulator 3, inquiry light is modulated by manipulator 3；When manipulator is in open mode, inquiry light, by arriving corner reflector 4 after manipulator 3, after corner reflector 4 reflects, again by manipulator 3, returns to photoreceiver 2 according to original incident direction；When manipulator is closed, inquiry light is irradiated on manipulator 3, blocked by manipulator 3, corner reflector 4 can not be arrived, now photoreceiver 2 will not receive the optical signal of return, realizing inquiry pumped FIR laser by manipulator 3 being carried out on-off control, making photoreceiver 2 receive coded light signal, thus the information that realizes is by B end to A end transmission.
Beneficial effect
Present invention aim to address space ranging and the Complex Problem that communicates, its advantage is on the basis with cooperative target distance measurement function conventional at present, by increasing manipulator before corner reflection prism, makes device have communication function, thus realizing range finding communication one.
