Description
Technical field
The present invention relates to a kind of laser illuminator, in particular, particularly relate to one utilize motor-driven eyeglass or
Mirror group realizes the laser illuminator that illumination spot directly switches between double-view field or many visual fields.
Background technology
In prior art the many employings of laser illuminator focus, continuous vari-focus mode, this zoom mode is in real world applications
Some occasion is the most inapplicable, focuses the light angle that mode is the most fixing, it is impossible to change the size of illumination spot, continuous vari-focus side
Although the angle excursion that formula contains is big, but changes to focal length from Radix Rumicis or change to the time used by Radix Rumicis from focal length
Long, but it is not appropriate for some and has only to two or more light angle, need not continuous vari-focus to angle switching requirement quickly
The application scenario of switching.
Summary of the invention
The present invention is for the shortcoming overcoming above-mentioned technical problem, it is provided that a kind of double-view field or many visual fields laser illuminator.
The double-view field of the present invention or many visual fields laser illuminator, including laser lens, laser instrument and control circuit, laser instrument
Producing laser under the effect of control circuit, laser light path in laser lens forms illumination spot；It is characterized in that: laser
Being provided with motor on camera lens, motor is connected with control circuit；It is fixed with on the output shaft of motor and can be placed in laser lens
The switching eyeglass switched in light path or between the light path of disengaging laser lens or mirror group are the biggest with the hot spot realizing sending
Switch between visual field and small field of view, meet different laser lighting demands.
The double-view field of the present invention or many visual fields laser illuminator, described motor is provided with encoder, encoder and control
Circuit is connected, with the rotational angle of output motor.
The double-view field of the present invention or many visual fields laser illuminator, the laser that described laser instrument sends is infrared band.
The invention has the beneficial effects as follows: the double-view field of the present invention or many visual fields laser illuminator, in the control of control circuit
Under effect, the laser that laser instrument sends light path in laser lens produces laser facula, to realize laser lighting.By swashing
Motor is set on light camera lens, and switching eyeglass or the mirror being placed in or departing from laser lens light path is set on the output shaft of motor
Group, relies on motor to order about switching eyeglass or mirror group rotates, it is achieved that laser illuminator switching between big visual field and small field of view,
The large and small hot spot sent is suitable to the illumination of different condition.Due to ordering about by motor, make eyeglass or the direct switching of mirror group, nothing
Zooming procedure, switch speed is fast, is suitable to angle switching is required quick occasion.
Accompanying drawing explanation
Fig. 1 is double-view field or the schematic diagram of many visual fields laser illuminator of the present invention；
Fig. 2 is the structural representation that in the present invention, switching eyeglass or mirror group are arranged in laser lens.
In figure: 1 laser lens, 2 laser instrument, 3 control circuits, 4 motors, 5 encoders, 6 switching eyeglasses or mirror group.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, give double-view field or the schematic diagram of many visual fields laser illuminator of the present invention, it is by laser lens
1, laser instrument 2, control circuit 3, motor 4, encoder 5 form, and shown control circuit 3 has collection, computing and control action,
Motor 4, encoder 5 are all connected with control circuit 3 with laser instrument 2.Control circuit 3 controls the laser powered sensor of laser instrument 2, laser
The laser that device 2 sends forms laser facula after the pipeline in laser lens 1, to realize illuminating effect.Motor 4 is arranged at laser
On camera lens 1, the rotational angle of motor 4 is measured by encoder 5, and by data transfer to control circuit 3, to realize
The control circuit 3 control to motor 4 rotational angle.
As in figure 2 it is shown, give the structural representation that in the present invention, switching eyeglass or mirror group are arranged in laser lens, institute
Show and on the output shaft of motor 4, be fixed with switching eyeglass or the mirror group 6 being placed in or departing from light path in laser lens 1, pass through switching
Eyeglass or mirror group 6 are placed in or depart from light path, and the laser facula that laser lens 1 can be made to send is carried out between big visual field and small field of view
Switching, to meet different lighting demands.
The relatively large spot that laser illuminator sends under big visual field, laser is broken up, and is suitable to illuminate on a large scale, and cooperation is taken the photograph
The image that camera obtains, the recognizable number-plate number.The relatively small light spot that laser illuminator sends under small field of view, the centrality of laser
Preferably, glass for vehicle window can be penetrated, it is achieved evidence obtaining that situation in car is taken pictures.
Owing to relying on the rotation of motor to realize eyeglass or mirror group direct switching in the optical path, visual field governing speed is fast,
Its switch speed is that the laser illuminator of continuous vari-focus is incomparable.Such as night is at road gate, utilizes laser lighting
Device and video camera are to vehicular traffic by null process, and vehicle is when bayonet socket, and laser illuminator is first in big field conditions, greatly
Laser facula under field conditions is broken up, and the image shot by video camera can recognize that license plate number；When vehicle further towards
Time, controlling motor 4 and be rapidly switched to small field of view illumination, under small field of view, the centrality of laser facula is preferable, can pass through glass for vehicle window,
Video camera is conducive to vehicle interior to be taken pictures evidence obtaining.Now, if using the laser illuminator of continuous vari-focus, owing to vehicle travels
Speed, then cannot realize the switching to small field of view of the big visual field within the time required；If using the laser lighting focused
Device, then cannot photograph the picture rich in detail meeting requirement.
