Abstract
A portable laser and its coding detector relates to a laser detecting device, the device is a cuboid box, comprising an attenuation slice, a filter, a condenser, a photoelectric detection tube, a receiving circuit and a counting circuit. The adjustable offset voltage and threshold are used for detecting the laser device having laser emission or not (the device can response to the laser whose wavelength is from 0.53 Mum to 1.342 Mum); the attenuation slices of different attenuation values are fixed in the metal rings, the attenuation values can be combined arbitrarily and used for detecting whether the energy can meet the requirement of lowest energy; the device can record the number of the laser pulses detected, which can probably judge whether the laser coding is correct. The detector can be putted in pockets and carried easily, which is a rare tool type apparatus for the production and using of laser devices and the maintenance workers.
Description
Technical field
The present invention relates to a kind of Laser Detecting Set, especially a kind of to the laser of the nonvisible wavelength portable laser that survey, that certain responding ability is arranged and the detector of coding thereof.
Background technology
Along with development of science and technology, laser is used widely in a plurality of fields.Militarily, range finder using laser, fire control system, laser radar, laser enemy and we identification and communication system, laser positioning instrument, laser target designator, laser disturb practical products such as firearms and various laser analog training aids to emerge in an endless stream, come out one after another.Then used multi-wavelength's semiconductor laser in the communication.These laser products, the major part that especially military laser product sends are the sightless laser of human eye.In addition, the laser that these energy heights are concentrated all has injury to human eye, and in certain distance, human eye can not be faced laser.Take what method to judge that these laser devices can normally send laser? send laser? the power of can summary judging laser power? can do you judge whether the coding of laser accurate by summary? this be laser device in production run, operational phase, the major issue that in maintenance process, must solve particularly.
At present, manufacturer is used to judge that the method whether invisible laser of laser product has laser to send has following several:
A kind of is that the monopulse laser that solid state laser sends is surveyed.The laser that sends as ND:YAG.This laser pulse power can reach MW class, so an optical lens commonly used focuses on, places a sheet metal on the focal plane of these lens, and laser that laser device sends and sheet metal bump against, and will flash and strike note.
A kind of laser that is noise spectra of semiconductor lasers is sent is surveyed.The laser energy that semiconductor laser sends is low, can not survey with the method for lens focus, observe with special-purpose night vision instrument.
Another kind is then with specific apparatus exploring laser lights such as energy meters.Various different wavelength of laser will be equipped with corresponding energy meter and probe.
Above detection method is all more loaded down with trivial details, more can not carry, and can not take into account multi-wavelength's laser and survey, and also dangerous big, must extreme care in the operation.These laser acquisition equipment have only professional production producer to be equipped with, and to use, the maintenance personal is used to judge invisible laser has or not and summary is judged and the power of laser energy and the portable laser detector of exploring laser light coding be yet there are no both at home and abroad.
Summary of the invention
The purpose of this invention is to provide a kind of portable laser of invisible laser and the detector of coding thereof.This detector can be realized following function:
1, exploring laser light has or not.Specifically, the peak power that JT-1 system in both detectable similar three generations's main battle tank (hereinafter to be referred as " JT-1 system ") high power semiconductor lasers sends is that hectowatt grade, wavelength are the laser of 904nm, the energy that detectable again similar PL66 formula 152mm terminal guidance ammunition armament systems laser target designators (hereinafter to be referred as " laser target designator ") send is the laser of 40mj, and the pulse energy that also detectable common laser range finder sends is the laser of 10mj.
2, the coding of laser pulse judged in summary.Promptly judge by surveying weekly phase coding number whether its coding is correct.For example, there is the coding of kind more than 30 in the JT-1 system, but total number of every kind of coding has difference: for example, the number that enemy and we discern the 00-01 sign indicating number is 406, and the 00-02 sign indicating number is 382, and the 00-03 sign indicating number is 430; " 11 " sign indicating number of digital communication sign indicating number is 144, and " 12 " sign indicating number is 168, and " 23 " sign indicating number is 192; The voice communication preamble code is 96 or the like.Again for example, laser target designator 4
#Sign indicating number is 301,74
#Sign indicating number is 307,75
#Sign indicating number is 313,76
#Sign indicating number is 320 or the like.Therefore, this detector can and show weekly that the laser pulse number that the phase receives comes summary to judge whether the laser code of tested equipment is accurate by record.Facts have proved that the confidence level that this simple and easy method is judged can reach more than 80%.Removed difficulty from complex proprietary and all purpose instrument test coding.
3, summary judges that can the output energy of laser reach minimum index request.This detector is provided with the attenuator of adjustable detection thresholding and multiple pad value.Can judge that by adjustment threshold level and change pad value can the laser energy that tested equipment sends reach basic energy value requirement.
This detector can send luminous indication immediately and carry out acoustic alarm after detecting the laser that laser equipment sends.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of portable laser and code detector thereof are made up of photoelectric receiving tube, receiving circuit, warning circuit, mu balanced circuit etc., it is characterized in that: the optical attenuator of some differential declines values is separately fixed in the measure-alike quoit, any quoit all can be connected with detection window by screw thread, and another quoit can be screwed in this quoit by screw thread again; The negative terminal of photoelectric receiving tube V0 connects the output of adjustable stabilized voltage supply by repeating resistance R0, positive termination coupling capacitance C1 and the current-limiting resistance R1 of photoelectric receiving tube V0, the A point of another termination Schmidt integrated circuit Sheffer stroke gate IC1 of coupling capacitance C1 also links to each other with the adjustable side of signalc threshold regulator potentiometer RP1.

Detector is exemplified below the detection scaling method whether the measured laser equipment satisfies minimum energy requirement:
1. the minimum energy requirement of supposing certain laser target designator is 30mj.Then at first select a laser target designator, and with its output energy adjustment be 30mj.
2. do not add attenuator at detector window, detector window is aimed at the laser output window of laser target designator, regulate RP2 and RP1, promptly progressively improve bias voltage and improve thresholding, so, necessarily can detect laser and count and sound and light alarm.Thus, can judge to have or not laser to send, and can write down and the coded pulse number that shows in the one-period.
3. screw on attenuator at detection window.By combined method, the attenuator of selected differential declines value.Always can find a value, make detector just not receive laser, promptly be in critical localisation.This position is exactly the position of the minimum energy requirement of laser target designator.If the pad value of other laser target designator stack, illustrates then that the laser energy of this target-designator output satisfies minimum energy requirement greater than this.
Detector is a rectangular parallelepiped box, and the common multimeter of its volume ratio is also smaller, can directly put into user of service's pocket, is easy to carry, and is production, the use of being engaged in the laser equipment, the instrument Sex apparatus that particularly the maintenance support personnel are rare.
