Abstract
The optical path device as one part for laser camera consists of support, laser, lens combination, motor and reflector. The lens combination is opposite to the hollow motor shaft, and the extending motor shaft has reflector mounted and reflecting hole in between. The present invention is used to project rotating laser beam to film, determine accurately the start end and stop end of scanning and form clear and accurate scanning result image on the film. The present invention has the advantages of simple mechanism, high stability, long service life, etc.
Description
Affiliated technical field
The invention belongs to the parts of laser camera, particularly a kind of light path device of laser camera.
Background technology
The light path system of existing laser camera adopts gas (CO mostly
2Or HiNe) not only cost height, serviceable life are short but also interchangeability is poor for laser instrument, this laser instrument, break down often, maintenance is inconvenient.The hexahedron catoptron processing request height that adopts, used adjustment lens require the optical accuracy height, complicated light path processes such as the laser beam process lens combination that laser instrument produces, hexahedron catoptron, adjustment lens, single face catoptron, thus make mechanism's complexity.
Summary of the invention
In view of the problem that the light path device that has laser camera now exists, the invention provides the light path device of the laser camera that a kind of mechanism is simple, stability is high, easy to maintenance.
The present invention is made up of support, laser instrument, lens combination, motor and catoptron.At the middle part of support fixed laser, front end at laser instrument is provided with lens combination, motor is contained on the support, be positioned at lens combination before, motor shaft is the hollow form axle, lens combination is over against the middle vacancy of motor shaft, external part one side at motor shaft has the light reflection hole, inject into the α angle facing to lens combination light, the α angle is between 30 °～60 °, adorn a catoptron at the hollow motor shaft external part, the light that sends from laser instrument is shone on the catoptron through lens combination, be focused into a bit, and beat on film from the ejaculation of light reflection hole.
The present invention can project the laser beam of rotation on the film, and accurate start point of location scanning of energy and scanning terminating point, forms clear and accurate diagnostic scan result on film.Advantage such as have that mechanism is simple, stability height, long service life, high conformity, failure rate are low, easy to maintenance.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1 support, 2 laser instruments, 3 lens combination, 4 motors, 5 motor shafts, 6 catoptrons, 7 films, 8 smooth reflection holes.
Embodiment
Referring to accompanying drawing, the fixing semiconductor laser instrument 2 at the middle part of support 1, front end at semiconductor laser 2 is provided with lens combination 3, motor 4 is contained on the support 1, and motor 4 is positioned at the front of lens combination 3, and motor shaft 5 is a hollow form, lens combination 3 is over against the middle vacancy of motor shaft 5, external part one side at motor shaft 5 has light reflection hole 8, adorns a catoptron 6 at the external part of hollow motor shaft 5, and catoptron 6 becomes the α angle with electrical axis.Being installed in the laser beam that the laser instrument 2 in the support sends gets on the catoptron 6 through light behind the refraction action of lens combination 3, arrive on the film 7 through light beam after the reflection of catoptron 6, simultaneously, the sensor that is installed on the scanister is transferred in the computing machine as the starting point of scanning and with this signal to the light beam that arrives film 7, through the control procedure of control circuit view data is passed through the laser beam flying of laser instrument 2 to film 7.Being installed in owing to catoptron 6 in the motor shaft 5 of motor rotating at high speed 4 makes laser beam along with motor rotating 4 forms the laser beam circular arc.And film 7 is placed in the scanning cylinder of semicircle, by control system control view data is all clearly scanned on the film 7.
