Specific embodiment
The following detailed description of specific implementation of the invention, it is necessary to it is indicated herein to be, implement to be only intended to this hair below
Bright further explanation, should not be understood as limiting the scope of the invention, and field person skilled in the art is according to above-mentioned
Some nonessential modifications and adaptations that summary of the invention makes the present invention, still fall within protection scope of the present invention.
The present invention provides a kind of laser angle calibrating installation and its methods, as shown in Figure 1, laser angle calibration cartridge
Laser 1, diaphragm and prover 2 including setting gradually on laser optical path direction are set, wherein the structure of prover 2 such as Fig. 1
Shown, the first, second, third and fourth side plate of prover surrounds the rectangular configuration with hollow cavity, wherein the first and third side plate it is opposite and
It is set on the direction vertical with laser optical path, second, four side plates are opposite and are set on the direction parallel with laser optical path；The
It is the opening of A that side plate center, which has an aperture, and aperture is provided on the inside of the third side plate being oppositely arranged and is greater than opening
The convex mirror 3 in aperture, the laser beam of laser transmitting, by opening, are then irradiated on convex mirror 3, convex mirror after diaphragm
3 light beam is reflected after be irradiated on the first side plate, be irradiated in second or the 4th again after the reflection of the first side plate on side plate；Diaphragm tool
There is aperture B, while setting can be by wiping out background veiling glare, guarantees that the laser beam of laser transmitting can be by (even if swash
Light light beam has certain deflection angle), and the deflection angle of the laser beam of laser transmitting meets certain angular range,
If laser beam after diaphragm is without deflection angle, and direct irradiation is to the center of convex mirror 3, then laser light
Beam is returned according to original route, during calibration, is adjusted by the transmitting beam angle means for correcting of laser itself sharp
The Laser emission angle of light device, to change the launch angle of the laser beam of laser, laser beam irradiates after passing through diaphragm
Onto convex mirror 3, it is irradiated on the first side plate after beam path will be changed after reflection.
The structure of prover 2 is fixed design, and the subsequent corrosion of convex mirror 3 is also the definite value after design, therefore with one
Determining angular illumination can be reflected to the laser beam of convex mirror 3 with fixed angle, because the structure of prover 2 is fixed,
In hollow cavity the 3 to the first side plate of convex mirror and the first side plate to second or the 4th the path of side plate be also fixed, the length in path
Degree is also fixed, and the reflection point of the first side plate and second or the 4th side plate is also fixed, therefore passes through optical design,
Prover is calibrated in advance, using after calibration structure and light path angle and length relation can be obtained by the light of laser
The deflection angle of beam, to carry out the angular adjustment apparatus of correcting laser itself by the calculated value of deflection angle, to realize laser
The calibration of device.
As shown in Figure 1, being both provided with scale and corresponding light on the inside of the first, second, the 4th side plate in concrete implementation
Sensor, optical flame detector sense that electric signal is issued when laser beam is sent to controller (not shown), and controller receives telecommunications
Determine the deflection angle and real-time display of the laser beam of the transmitting of laser at this time after number, furthermore the first, second, the 4th side plate
Outside is provided with indicator corresponding with scale label, right while inductor senses laser beam during calibration
The indicator of scale label is answered to shine, so as to intuitively read corresponding deflection angle, to adjust device with laser
Adjusting parameter be compared, the calibration of laser is realized by calibration adjustment device.
In addition, the setting of convex mirror is so that incidence angle has bigger angle outgoing after reflection, in this way in the first side plate
Reception when, it is necessary to the first side plate long enough, but cross and grow side plate length and will increase volume, and the effect of measurement can be reduced
Rate, therefore dielectric layer is set on the correspondence optical flame detector of the inside of the first, second, the 4th side plate, according to Snell principle: n0sin
θ0=n1sinθ1, wherein n0And n1The respectively refractive index of air and dielectric layer, θ0And θ1Respectively incidence angle and the angle of emergence, that
If the refractive index n of dielectric layer1Greater than n0, then the angle of the angle of emergence can become smaller, if corresponding in same ranges of incidence angles
Interior, the setting length of corresponding optical flame detector can reduce, then reduction can be arranged in the length of corresponding side plate.Therefore, it is situated between
The refractive index n of matter layer1Greater than the refractive index n of air0, such set-up mode reduces the setting length of side plate, so as to subtract
The volume of small prover 2, reduces the volume of entire calibrating installation.
The present invention also provides a kind of angle calibration system methods, in turn include the following steps:
(1) control laser emits the parallel laser light beam of not angular deflection, so that laser beam after diaphragm by shining
It is incident upon the center of convex mirror, if optical flame detector does not sense laser beam, enters step (2)；

(3) laser beam is after convex mirror emits, with the first measurement angle transmitting, to the first side after first medium layer
Plate, when the photoreceptor on the first side plate senses the first sensed position of laser beam, sending includes the first of first position
Electric signal is to controller, and the indicator of corresponding scale shines；
(4) laser beam is after the transmitting of the first side plate, with the second measurement angle transmitting after first medium layer, by second
Or the 4th after dielectric layer to the photoreceptor on the second or the 4th side plate, second or the 4th side plate sense laser beam second or
When third sensed position, sending include second or the third place second or third electric signal to controller, and corresponding carve
The indicator of degree shines；
(5) the corresponding deflection angle in first position and second or the corresponding deflection angle of the third place are compared, if partially
