Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Attached drawing 1 shows the photoelectronic collimating and positioning system of a kind of laser tracker of embodiment according to the present invention.
Specific embodiment
In the following detailed description, many details are proposed, in order to complete understanding of the present invention.But
It will be apparent to those skilled in the art that the present invention can not need some details in these details
In the case of implement.Below to the description of embodiment just for the sake of provided by showing example of the invention to it is of the invention more
Understand well.
Below in conjunction with attached drawing, the technical solution of the embodiment of the present invention is described.
As shown in Figure 1, the present invention provides the photoelectronic collimating and positioning system of a kind of laser tracker, comprising: photoelectric position-sensitive
Detector (Position Sensing Detecter, PSD), control system, servo motor, reflecting rotating mirror, spectroscope, interference
Light path module and laser head；The laser head transmitting light beam passes through optical interference circuit to spectroscope；Light beam at the spectroscope its
In be reflected into photoelectric position-sensitive detector all the way, another way light beam reflexes to reflective mirror；The photoelectric position-sensitive detector and servo
Motor is connected, and the servo motor drives reflecting rotating mirror rotation, changes the direction of the light beam into photoelectric position-sensitive detector,
Reduce the deviation signal of the light beam, realizes the dynamic tracking measurement of target.
According to an aspect of the present invention, servo motor is powered by power supply module.
According to an aspect of the present invention, power supply module includes power supply line, city and stand-by power supply route.
According to an aspect of the present invention, stand-by power supply route include solar panel and with it is described too can solar panel phase
Even solar energy storage charger.
When system works, by tracking mirror homed on its target target mirror, target mirror is the measuring beam that laser issues
The optical reflector of one embedded prism of corner cube, for measuring and tracking.The laser beam that follower head issues is entered by optics microscope group
It is mapped on reflecting rotating mirror, light beam is reflected the light into target mirror, reflected through target mirror by tilting mirror adjustment level and pitch angle
Line is parallel to elementary beam return.After the laser beam of return reaches spectroscope, light beam is by reflection people PSD all the way, another way light beam into
Enter laser interference Range Measurement System.Light beam into PSD is used to track target mirror, when light beam enters optical reflector pyramid
When vertex position, Returning beam does not have positional shift relative to incident beam, and PSD output signal is zero, at this time at control system
In static measurement；When target mirror is mobile, Returning beam generates position deviation, PSD output error letter relative to incident beam
Number.Tracking mirror rotation is driven by the control signal drive motor that DSP intelligent control algorithm calculates and outputs, changes and enters target
The beam direction of target mirror, reduces deviation signal, to realize the dynamic tracking measurement of target.When measurement, it is desirable that PSD is visited in real time
Position of the laser beam returned through target mirror on photosurface is surveyed, and the synchronous driving of position offset signal is controlled to tracking
Unit processed carries out calculation process.
The present invention solves the FAQs such as low, the dynamically track effect difference of laser tracker positioning accuracy, have tracking with
Positioning accuracy is high.The good feature of dynamically track effect.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
