Description
Technical field
The invention belongs to remote sensing survey technical fields, and in particular to laser detection system warship turret design visits laser
Examining system is suitable for naval vessel.
Background technique
Raising of the national consciousness to marine eco-environment attention degree has promoted various remote sensing survey technologies in marine environment
Application and development in monitoring.Microwave imaging and optical imagery carry out application in the field, in addition to this in recent years by
Jian You scientific research institutions attempt to realize the monitoring to marine environment by Laser Detection Technique from laboratory applications airborne platform.
Laser Detection Technique is to expose to excitation laser on object, carries out substance identification by collecting echo.Laser
Detection system generally has the devices such as laser, optical module, photodetector composition.The quality of whole system be mainly distributed with
On laser (occupy total quality 1/2 or 2/3).Existing laser detection system mostly visits laser, optical module and photoelectricity
Survey device to be placed on a plane (platform), whole system quality caused more to concentrate, cause to manually change pitching orientation or
It is extremely difficult to be loaded into the relatively bulky turntable of quality.
Summary of the invention
The present invention provides a kind of whole reduction turntable weight, the laser for being conducive to the popularization of laser detection system warshipization is visited
Examining system warship turntable.
A kind of laser detection system warship turntable of the present invention, including turntable, laser, optical module, photodetector,
It is characterized in that, laser is placed on the pedestal of turntable, opens up optical transmission window, laser emitting in turntable pitching Pivot axle
Laser passes through optical transmission window, is emitted turntable through optical module, exit direction is parallel with the optical axis of photodetector or coaxial heavy
It closes.
Preferably, optical module includes the first reflection microscope group and the second reflection microscope group, and the first reflection microscope group passes through
Fluting is fixed on orientation rotation seat above turntable pitching Pivot axle, is placed on pitching Pivot axle hollow part, and
And it is located at the intersection of turntable orientation rotation central axis and turntable pitching Pivot axle, it is rotated in turntable pitching Pivot axle
When, the first reflection microscope group position does not change；Second reflection microscope group is mounted on the outgoing platform of turntable.
Preferably, laser is reflected microscope group with 45° angle incidence first and is gone out with 45 ° of angles of emergence by optical transmission window
It penetrates.
Preferably, the laser that laser issues enters the first reflective microscope group after beam expanding lens expands.

Specific embodiment
As shown in figures 1 and 3, a kind of laser detection system warship turntable of the present invention, including turntable, laser, optics group
Part, photodetector, laser are placed on the pedestal of turntable, open up optical transmission window, laser in turntable pitching Pivot axle
Device shoot laser passes through optical transmission window, is emitted turntable through optical module, exit direction it is parallel with the optical axis of photodetector or
Same overlapping of axles.
The difficult point of technical solution of the present invention is to guarantee that laser emitting path is not when turntable carries out orientation and pitching rotates
It is blocked, and the change direction of optical axis is consistent with the adjustment direction of turntable.Wherein optical transmission window open up need to meet laser into
Enter and is not blocked.For laser emitting laser after beam expanding lens, beam divergence angle reduction makes laser direction in turntable internal transmission
Property is more preferable.Optical transmission window setting uses special plated film, and it is higher can to guarantee that laser has when turntable carries out pitch rotation
Cross rate.
In order to guarantee the preferential selection following scheme of the realization present invention of scheme, but be not restricted to that this programme:
Reflecting microscope group includes the first reflection microscope group and the second reflection microscope group, and the first reflection microscope group passes through in turntable pitching rotation
Fluting is fixed on orientation rotation seat above mandrel, is placed on pitching Pivot axle hollow part, and be located at turntable orientation
The intersection of Pivot axle and turntable pitching Pivot axle, in the rotation of turntable pitching Pivot axle, the first reflecting mirror
Group position does not change；Second reflection microscope group is mounted on the outgoing platform of turntable.Laser is by optical transmission window, with 45° angle
Incidence first is reflected microscope group and is emitted with 45 ° of angles of emergence.Selection this programme is installed easy to operate because cost of implementation is lower.
Other are for example added control system and realize the automatic control of reflective microscope group to reach the methods of invention requirement and can improve equipment cost.
Operating procedure of the invention is as follows:
As depicted in figs. 1 and 2, laser is mounted on to rotary table base center vertically upward；
One beam expanding lens is installed, beam expanding lens completion expands laser emitting laser, reduces it and transmitting above laser
Divergence loss in the process；
Laser is after expanding, and through the optical transmission window in pitching rotary shaft, is mounted on turntable pitching center with 45° angle incidence
With the reflecting mirror in the first of orientation rotation center intersection the reflection microscope group, and it is emitted with 45° angle；
Laser after transmitting enters the light path system that reflecting mirror forms in the second reflection microscope group with 45 °, is emitted turntable；
As shown in Fig. 2, laser is reflected through reflection microscope group behind the angle turntable orientation rotation Φ, smooth outgoing is not blocked, is emitted
Direction changes the angle Φ, consistent with orientation rotation angle.Laser emitting direction is orthogonal with direction direction of rotation, so laser is with orientation
It rotates the change of angle and changes.
The design of above-mentioned turntable ensure that the laser emitting light for being mounted on turret base not by turntable pitching, orientation rotation
Block, ensure that laser detection system warship useization promote.
The maximum equipment laser of quality in laser detection system is placed on the pedestal of turntable by the scheme that the present invention uses
On, reduce the load of turntable.Biggest advantage of the present invention is reduction of turntable load weight, thereby reduces turntable entirety
Weight, the reduction of load weight, while reducing the difficulty of turning table control and improving control precision.
