Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Fig. 1 ~ 3, the invention mainly comprises housing 1, Amici prism 2, CCD camera 3, rear end cap 4 and laser heads 5.
Prism cavity and camera shooting head cavity are successively arranged in housing 1 from front to back, is divided in the prism cavity by the way that glue is fixed
Prism 2,
The Amici prism 2 is 45 ° of Amici prisms, and the front end face of Amici prism 2 is incidence surface 2.1, the incidence surface of Amici prism 2
2.1 stretching housings 1 and when detecting contact need the fiber glass stick calibrated.The side of Amici prism 2 is light splitting surface.
The prism cavity side is equipped with laser head cavity, and laser head 5, the entering light head contact of laser head 5 are inserted into laser head cavity
The light splitting surface 2.2 of Amici prism 2.
The camera is intracavitary to be equipped with CCD camera 3, and 1 tail end of housing removably connects rear end cap 4 by connector,
CCD camera 3 is pressed in laser head cavity by rear end cap 4.
The rear end cap 4 is equipped with interface slot 6, and the signaling interface of CCD camera 3 is stretched out from interface slot 6 and external letter
Number pipeline.
The working principle of the invention is: in testing calibration, fiber glass stick being attached to the incidence surface of Amici prism 2
On, the laser that laser head 5 issues is entered in Amici prism by light splitting surface, is then refracted to fine glass plane rod end through plane of refraction
On, it is reflected on the imaging end face of CCD camera 3 and is imaged again.If fiber glass nose face is a plane, reflect
Light is imaged at the center of CCD camera 3.If fiber glass nose face is the end face with angle, reflected light is in CCD
The imaging of camera 3 deviates center, and the distance of deviation corresponds to the angle in fiber glass nose face.Spin fiber glass bar, instead
It penetrates light and represents angle value at fiber glass plane rod end different location in the imaging position of CCD camera 3, to realize optical fiber glass
The detection of glass plane rod end angle, and position can be adjusted according to result and be straightened.
