Abstract
The utility model relates to a nonlinear meter for laser detectors, which is an instrument for measuring the nonlinearity of a laser detector. The nonlinear meter for laser detectors is provided with an instrument which is composed of a one-half wave plate, a polarizing prism, a Gran-typed laser beam splitting prism, a reflector, an optical shutter, etc., referring to the present status of lacking the nonlinear meter for laser detectors and that the devices near to the function of the nonlinear meter for laser detectors have low testing precision. The nonlinear meter for laser detectors can make one beam of polarization laser resolved into e light and o light beams, the light intensity and beam splitting ratio of which all can be continuously regulated. By utilizing the responses of the e light and the o light beams on the laser detector, the nonlinearity of the laser detector is quickly and accurately measured.
Description
The utility model is a kind of instrument of micrometric measurement laser detector non-linear parameter.
At present, still there is not the nonlinear instrument of this mensuration laser detector.The device close with the utility model function has reference detector comparison method proving installation, standard filter plate method proving installation, rotation polariscope method proving installation etc.All these devices and their employed method of testings all depend on the measurement to another parameter, and the error of measurement is all come out with the apparent non-linear behavior, and measuring accuracy is not high.In addition, in incoherent light radiotechnology field, useful method of superposition is measured the nonlinear device of detector.In this types of devices, all to use up as work with incandescent light, this light does not possess the characteristics of laser beam power density height, the uneven very thin quasimonochromatic beam of light of distributed pole.The non-linear behavior of laser detector when accepting laser emission and accept the incoherent light radiation is not the same.
It is a kind of high-precision that the purpose of this utility model is to utilize superposition principle to develop, and do not rely on the direct non-linear analyzer of using up as work with laser of laser detector to another parameter measurement.To improve measuring accuracy, shorten test period.
Fig. 1 is the non-linear analyzer synoptic diagram of laser detector, and wherein (1) is Glan type laser beam splitter prism.(2) be reflective mirror, (3
A) (3
B) be optical gate, (4) are ahrens prism, (5) are 1/2nd wave plates, (6
A) (6
B) (7) be governor motion, (8) are casing, (9) are structure member.
Fig. 2 is non-linear analyzer optics of laser detector and index path, and wherein (L) is the incoming line polarized laser beam, and (e) (o) is the output laser beam.
The utility model can be by following scheme implementation: on linearly polarized laser (L) transmission direction optical axis, be provided with successively 1/2nd wave plates (5), ahrens prism (4), Glan type laser beam splitter prism (1), in e light beam splitting direction optical gate (3 arrangedA), in the other o light of Glan type laser beam splitter prism (1) beam splitting direction a distance, speculum (2) is arranged, at the mirror reflects beam direction optical gate (3 is arrangedB), on 1/2nd wave plates (5) side governor motion (6 is arrangedA), on ahrens prism (4) side governor motion (6 is arrangedB), on reflective mirror (2) side governor motion (7) is arranged. Governor motion (6A〕〔6
B) all adopt the worm gear-endless screw mechanism with self-lock ability. Governor motion (7) is made of a ball-joint mechanism. Optical gate (3A〕〔3
B) be pneumatic optical gate, the opening and closing of optical gate is to be promoted by the compressed air in the air bag. Glan type laser beam splitter prism can be decomposed into polarized laser beam the mutually perpendicular e light in polarization direction, o light two light beams. Transfer the governor motion (6 of 1/2nd wave platesA), but the power of synchronous change e light, o light light beam. The governor motion (6 of tuningout light prismB) can continuously change the splitting ratio between e light, the o light light beam. Transfer the governor motion (7) of reflective mirror can change o light direction of beam propagation, make o light light beam superimposed with e light light beam or separate. Optical gate (3A〕〔3
B) can control respectively e light and o light light beam, they are exported respectively or simultaneously output. Because the utility model can make a branch of linearly polarized laser be decomposed into the mutually perpendicular e light in polarization direction, o light two light beams, simultaneously, realized the intensity of e light, o light light beam and splitting ratio continuous setup effectively, therefore when make e light, when o light light beam acts on the laser detector sensing element, can utilize e light, o light to act on respectively the response on the laser detector sensing element, and they make the result of time spent response simultaneously, record rapidly, accurately the non-linear of laser detector. Thereby solved the laser detector nonlinear determination problem of using up as work with laser that does not rely on another parameter measurement. The appropriate section of casing (8) has Laser Transmission hole and observation window. It is observed sheet and makes with translucent pmma material, is beneficial to the laser emission safeguard protection.
The utlity model has following advantage: the nonlinear parameter that can accurately measure laser detector and laser acquisition instrument; The test dynamic range is more than 40 decibels; Compact conformation, easy to operate, test rapidly.The utility model can satisfy the scrutiny needs to the laser detector non-linear parameter, also can be used for the quality testing of conventional laser product.
The utility model is except that using by above method, also can be by following scheme implementation: after choosing satisfied reference detector with this utility model, regulate governor motion (7) separately with e light, o light, the non-linear analyzer of laser detector that the utility model can transfer to quickly and easily with the work of reference detector comparison method uses, as conventional batch testing instrument.It can be used as a splitting ratio and beam intensity equal continuously controllable laser beam splitter device or laser attenuator assembly again and uses, and is used for other laser detection work.
