Description
Technical field
The application is related to distance-measuring equipment, more particularly to a kind of laser scanning and ranging equipment.
Background technology
Optical scanner distance-measuring equipment is the equipment that a kind of use collimated light beam carries out contactless target object scanning range finding.
By the way that a range of rotation will be carried out for the collimated light beam (laser) found range, you can realization is entered to object in the environment of place
Row scanning range finding, and extract the profile information of environment.
Current optical scanner range unit is had plenty of Laser emission reception device itself rotation but is powered by slip ring,
Some use belts or gear drive, this is several all to have that service life is short and volume is larger.Some range units
It is motionless sending and receiving apparatus, scanning range finding is accomplished by reflective mirror irradiation, and speculum manufacture craft difficulty is larger, if not
Smooth to may result in light angle biasing, reflecting effect is bad to cause light transmitting and receiving efficiency relatively low so that measurement distance
It is restricted.Some rangefinders are to scan range finding using triangle telemetry, and this kind of telemetry debugging difficulty is high, and measurement distance is short.
As a example by launching or receive reflected light coordinating one or more pieces speculums, existing two kinds of conventional range findings of structure
Equipment, Fig. 1 and Fig. 2 show the brief configuration figure of the distance-measuring equipment of prior art, as depicted in figs. 1 and 2, its use (one or
It is multiple) speculum and its optical axis is swung whole 360 degree one week, in any structure so that the light of (one or more) mirror
Axle and make this (one or more) mirror rotation motor overlapping of axles.
Distance-measuring equipment construction in Fig. 1 uses double-axis motor 420, and common rotating shaft 410a and 410b is from the motor
420 vertically extend, and on the one hand make the scanning mirror 430 on axle 410a, on the other hand make the receive mirror on axle 410b mutually the same
Install on ground.Light from the output of beam projector 450 is made to deflect and is projected by projection lens 470 by scanning mirror 430
On object to be illuminated.Reflection light from scanned object enters light receiver 460 by receiving lens 480.This knot
The motor arrangement of the distance-measuring equipment of structure is between scanning mirror and receiving lens so that the interval between scanning mirror and receiving lens
Larger, light path transmitting-receiving is not serious coaxial, and blind area is big, closely performs poor, and the center for being additionally, since optical system is rangefinder
Center, and rangefinder extends vertically, so limitation will be produced to how to install rangefinder.
Distance-measuring equipment construction in Fig. 2 uses motor 420, rotary shaft 410c to be protruded upward from the motor, and will
Double scanning/receive mirror 490 is arranged on rotary shaft 410c.From beam projector 450 output light by the projector 500,
It is reflected down by semitransparent mirror 510, and is radiated in double scanning/receive mirror 490；The light for reflecting there passes through mirror
490 deflect and project on object to be illuminated to the left.Reflection light from scanned object passes through scanning/receive mirror 490
Upward deflect, transmitted by semitransparent mirror 510, by receiving lens 520, and enter light receiver 460.The survey of this structure
Realize that transmitting-receiving is coaxial by semitransparent mirror away from equipment, but translucency is approximately equivalent to the half of ordinary lenses, sends and receives
Have lost a large amount of luminous energy.And employ double scanning/receive mirror come reflect scanning light beam and receive light, both phases may be made
Influence is produced between mutually and noise is formed, therefore limits the radiation receiving sensitivity and accuracy of distance-measuring equipment.
In such distance-measuring equipment, asking for the reduction of the light utilization efficiency caused by speculum reflectivity problem in itself is brought
Inscribe, and speculum needs to ensure the fixation of precision at work, additionally, the flatness manufacture craft difficulty of speculum is big, reflection
Mirror reflecting surface out-of-flatness causes projecting beam or the reflected beams angular deviation, causes light utilization efficiency low, therefore to design and producing
This kind of scanning range unit brings very big challenge, and causes the relatively costly of this kind of scanning range unit.Meanwhile, complicated light
Equipment also increases the size and weight of device.
In current existing some distance-measuring equipments, the distance-measuring equipment of Laser emission reception device itself rotation is occurred in that,
But this kind equipment is to realize that rotary part is powered and communicated, it is often necessary to which electric signal is passed between realizing rotary body using conducting slip ring etc.
Pass.And rotary unit generally realizes rotation using the kind of drive of belt.This greatly affected the life-span of this kind of device.And
The overall volume of distance-measuring equipment is directly increased using belt transmission.
