Description
Technical field
The present invention relates to a kind of detectors, and in particular to a kind of portable light shaft detection instrument and its method.
Background technology
Long distance laser range-measurement system and laser radar system etc. are all using transmitting laser irradiation to target surface,
The reflected optical signal of collection with large aperture shots is taken, and is focused on highly sensitive APD photodetectors, into
The conversion of traveling optical signal to electric signal carries out ranging, the identification tested the speed with target by the measurement to transmitting and receiving time difference
Deng before putting into formal use, it will usually carry out high-precision coaxial degree detection, it is therefore an objective to allow and aim at optical axis, transmitting optical axis
Keep high-precision coaxial with optical axis is received, this is also laser ranging system and the high-precision important leverage of laser radar system.
At present to mechanical axis, transmitting camera lens and there are two ways to receiving camera lens progress concentricity detection：One, using profit
Focal position calibration is carried out with optical axis is received to transmitting with heavy caliber condenser lens and CCD camera, it is right by correlation calibration position
Transmitting carries out the adjusting of optical axis with the system of reception, makes its position consistency, carries out concentricity detection.Two, recessed using heavy caliber defocus
Face speculum and CCD camera carry out focal position calibration to transmitting with optical axis is received, by correlation calibration position, to emitting and connecing
Receipts system carries out the adjusting of optical axis, makes its position consistency, carries out concentricity detection；
Laser ranging system and laser radar system are all the high precision instruments for having laser light source as transmitting light source.The
The heavy caliber condenser lens used in a kind of method generally requires bore and accomplishes 200mm, and this lens are due to processing technology hardly possible
Degree is very big, it is caused to involve great expense, and can make that the production cost increases, to reduce the price competitiveness of product；Second of side
Although in method with the concave mirror of defocus instead of bigbore condenser lens, cost reduction some, due to it
It is very thick and heavy, it has not been convenient to carry it is outgoing, once asking of occurring in the environment of work of laser ranging system or laser radar system
Topic is related to transmitting and reception system, then can not school axis again under mal-condition in the wild according to such method, it is necessary to send back to
The military region or manufacturer repair, and influence very much working efficiency.So those skilled in the art's optical axis detection urgently to be resolved hurrily
Of high cost, detecting instrument is excessively heavy, it has not been convenient to carry and go out, lead to problems such as working efficiency low.

Target aims at microscope group one end and observes bright spot, and adjusting gun sight makes bright spot clearly be located at the center of crosshair, locks gun sight, closes
Close visible light source.
8. a kind of portable light shaft detection instrument as claimed in claim 5, which is characterized in that transmitting optical axis school axis, open and swash
Light device, laser are incident on attenuator via transmitting microscope group, and attenuator is placed with transmitting optical axis at 45 degree, a part of light reflection to gear
On tabula rasa, another part light enters second and turns to prism, adjusts pitching and the azimuth of transmitting microscope group, laser is made to converge to CCD
On the receiving plane of camera, position, and save location information are demarcated.
9. a kind of portable light shaft detection instrument as claimed in claim 5, which is characterized in that receiving optical axis school axis, simulated light
Source is mounted in metal baffle, and metallic plate blocks analog light source in side, and side shines, and analog light source is received mirror by light echo
Group lower opening is put into, and opens analog light source, and analog light source sends out smooth directive APD photodetectors identical with laser wavelength
Receiving surface is reflected into light echo by APD photodetector receiving surfaces and receives microscope group, passes through achromatism microscope group and light splitting rib

Transmitting laser spot position it is consistent, after regulating by light echo receive microscope group locking, optical axis calibrator complete.
10. a kind of portable light shaft detection method, which is characterized in that the method includes
Calibration optical axis detector precision is adjusted, makes the receiving plane of visible light source and CCD camera in achromatism microscope group focal plane
Position；
Laser range finder is directed at optical axis detector, fine tuning target aims at microscope group, it will be seen that light hot spot images in target gun sight
Group center, pitching and azimuth of the fine-tuned emission microscope group with light echo reception microscope group by the transmitting of laser range finder and receive optical axis
It is calibrated；
Using observation visible light spot, calibration transmitting and position of the light spot received in the same CCD camera, fine tuning target aims at
Microscope group, transmitting microscope group and light echo receive pitching and the azimuth of microscope group, ensure that target aims at optical axis, Laser emission optical axis and returns
Optical signal receives the consistency of optical axis.
