Description
Technical field
The present invention relates to laser camera, particularly the light path device of laser camera.
Background technology
At present, the light path device of laser camera adopts gas (CO mostly
2Or Hi, Ne) laser instrument, the hexahedron catoptron processing request height that is adopted, used adjustment lens require the optical accuracy height, the laser beam that laser instrument produces is through complicated light path processes such as lens combination, hexahedron catoptron, adjustment lens, single face catoptrons, thereby make complicated integral structureization, this thus laser instrument not only cost is short high serviceable life, and interchangeability is poor, break down often, maintenance is inconvenient.
Summary of the invention
The objective of the invention is defective, provide a kind of simple in structure, stability height, the light path device of laser camera easy to maintenance for the light path device existence that overcomes existing laser camera.
Light path device of the present invention, comprise support, laser instrument, optical fiber lens, scan module and catoptron, its main points are to allow other arbitrary position of bending range support can the fixed fiber lens combination at mid-stent or optical fiber, do not focus on and do not influence laser beam, a stationary mirror is equipped with in axial intersection axial and scan module in the optical fiber lens group, and scanning reflection mirror is assemblied on the scan module axle.
The stationary mirror at 43 °～46 ° of angles of an inclination axially is housed with the axial intersection of scan module in above-mentioned optical fiber lens group.The scanning reflection mirror at the 43 °～46 ° of angles that tilt is housed at an end of scan module axle.The light that sends from laser instrument is shone on the stationary mirror through the optical fiber lens group, through shining on the scanning reflection mirror after the reflection, after scanning reflection mirror focus on the film.
The present invention compared to the prior art has significant advantage and effect:
(1) have simple light path process, because designs simplification, light path only shines stationary mirror through the optical fiber lens group, and then reflexes to scanning reflection mirror, finally focuses on the film, has simplified many than the complex optical path process of known technology.
(2) owing to adopted photodiode the laser beam of rotation can be projected on the film, and accurately start point of location scanning and scanning terminating point, the clear and accurate diagnostic result on film, formed;
(3) owing to designs simplification, the light path process is few, owing to adopted semiconductor laser so stability to be improved significantly, makes its long service life simultaneously, high conformity, and failure rate is low, and is easy to maintenance, and production cost is also reduced significantly.
