Description
Technical field
This application involves range sensor, in particular to a kind of micromation laser pulse ranging scanning means.
Background technique
With the rapid development of national intelligence equipment industry, laser pulse ranging scanning means, which is used as, has detection periphery feelings
The core sensor of condition obtains extensive promotion and application in industrial control field；At the same time, complete machine is equipped with to intelligence
The requirement of miniaturization is higher and higher, and laser pulse ranging scanning means demand miniaturization is also more and more clear.
Traditional laser pulse ranging scan device (hereinafter referred to as " conventional apparatus ") is generally using " transmitting-receiving as shown in Figure 1
It is coaxial " structure, including laser emitter 11 and laser pickoff 26,11 lower end of laser emitter is provided with Laser emission sleeve
16 and the L-type light cylinder 32 that is rotatably connected with Laser emission sleeve 16, the corner of the L-type light cylinder 32 be fixedly installed with
The reflecting mirror 31 at emergent ray angle at 45 °, the diameter of the reflecting mirror 31 is greater than the outer diameter of Laser emission sleeve 16, also greater than L
The outer diameter of type light cylinder 32 is equipped with reflective mirror 18, the outgoing that laser emitter 11 issues in 16 outer cover of Laser emission sleeve
Light is propagated in Laser emission sleeve 16 by, by 32 directive measured object of L-type sleeve, emergent ray exists after the reflection of reflecting mirror 31
Measured object surface reflection forms reflection light, and at least part reflection light propagates to L-type set along the reverse direction of emergent ray
On reflecting mirror 31 outside cylinder 32, incorporated by reference to Fig. 1, directive reflective mirror 18 after reflection light is reflected by reflecting mirror 31, by reflective mirror
Directive laser pickoff 26 after 18 reflections, issues emergent light according to laser emitter 11 and laser pickoff receives reflected light
Time difference can calculate the distance of testee in conjunction with the light velocity, be based on above-mentioned laser pulse ranging principle, pass through motor driven
Reflecting mirror 31 rotates, and then drives the rotation of laser ranging optical path, realizes the scanning and measurement to two-dimensional scene.In above scheme
In, 45 ° of reflecting mirrors 31 optical path switching device important as one rolls over Laser emission optical path and laser pick-off optical path
It returns, occupies biggish space thus.Moreover, driving laser optical path to rotate by 45 ° of reflecting mirrors 31 of rotation, and then realize rotation
Turn scanning, would have to be reserved with big quantity space so that 45 ° of reflecting mirrors 31 can rotate freely.
In addition, swashing since laser pulse ranging scanning means is to receive the device that eyeglass is " receiving antenna " with optics
Under conditions of the conditions such as light emitting power are constant, range capability is directly proportional to the optics reception usable area of eyeglass, to realize
Certain distance ranging demand, the area for needing that optics is made to receive eyeglass reach certain size requirement.Therefore, for shown in Fig. 1
Laser pulse ranging scanning means for, optics receive center of lens part area occupied by laser emitting portion, cause
Optics receives center of lens part and is not available, and can be reduced with receiving area.Due also to Laser emission sleeve design is in main optical path
In, the path of part reflection light return has been blocked, has caused optics to receive corresponding region on eyeglass and is substantially at invalid state, from
And it is further reduced the available receiving area for receiving eyeglass, therefore, it is necessary to the optics for using outer dimension very big to receive eyeglass
Smaller outer dimension optics receives eyeglass with regard to attainable performance on realization theory, leads to laser pulse ranging scanning dress as a result,
The overall volume set is bigger than normal.
Incorporated by reference to such as Fig. 2 a, Fig. 2 b and Fig. 3, for example, actual outer dimensions are that the optics that diameter is 30mm receives eyeglass,
Capture area just corresponds to the theoretical receiving area that the optics that diameter is 18mm receives eyeglass.For the survey for guaranteeing conventional apparatus
Do not decline away from ability, that is, guarantee that the capture area of optics reception eyeglass does not reduce, in general, being received by increasing optics
Eyeglass outer diameter makes up the damage of capture area caused by the above problem to improve the method for optics reception eyeglass overall dimensions
It loses.
Further, match since the outer diameter of 45 ° of reflecting mirrors needs to receive eyeglass outer diameter with optics, i.e. 45 ° of reflecting mirrors
Size be by optics receive eyeglass outer diameter determines, therefore, if optics receive eyeglass outer diameter increase, need
The outer diameter of 45 ° of reflecting mirrors is wanted also to increase accordingly, in turn, the revolution space reserved for 45 ° of reflecting mirrors also accordingly increases, and causes
The overall volume of conventional apparatus further increases.
