The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.In the case where not conflicting, implement below
Feature in example and embodiment can be mutually combined.
The sounding optical system that the present embodiment is provided can be applied to high-precision scanning laser mapping radar, belong to its core
Center portion part.The sounding optical system provided using the present embodiment, can be based on time-of-flight method, calculate modulation Laser emission
With the time difference of return, obtain light path, and then obtain detecting the range information of target.
As shown in figure 1, sounding optical system includes：LASER Light Source 11, through hole speculum 12, reflecting prism 13 and light
Reception system 14；The laser beam that LASER Light Source 11 is launched, through the through hole of through hole speculum 12, by the anti-of reflecting prism 13
Target acquisition space is irradiated to after penetrating, when laser beam target acquisition space illumination to detection target when, the laser beam warp
Detection target scattering is crossed, after the echo of formation is reflected by reflecting prism 13 and through hole speculum 12 successively, light-receiving system is irradiated to
On system 14.
The optical system that the present embodiment is provided receives mode from axis light so that field of view of receiver is not a problem, and uses
One, which receives one, sends out, and reduces optical element, reduces the design difficulty of optical receiver system, simultaneously so that whole sounding optics
System bulk is small, compact conformation.
Further, reflecting prism 13 can rotate, to realize the scanning of vertical direction (i.e. z-axis direction is shown in Fig. 1),
Sounding optical system can (i.e. the x-y plane of x-axis and the y-axis composition shown in Fig. 1) rotation in the horizontal plane on the whole.Tool
Body, reflecting prism 13 is reflex prism.Reflex prism can regard its central symmetry axis as its rotary shaft.

Z-axis has deflected 10 degree, be to realize -40 ° -+60 ° vertical scanning in target acquisition space, i.e., reflex prism realize -
20 ° -+30 ° of deflection.Therefore, the optical system scanning field of view that the present embodiment is provided is big.
The selection of reflecting prism 13 is set to reflex prism.The reason for this set is：Selected in now universal laser radar
Galvanometer, causes the scanning angle of existing laser radar to be limited, and because the inherent characteristic that light beam reflects can not be met simultaneously
The condition of two scanner uniform scannings, can cause the distortion of scan image.And mechanical scanning angle is required in this optical system
For 50 degree, and reflex prism can ideally scan 120 degree.Size in view of launching laser facula, from this angle
Seem it is contemplated that the face number of the reflective surface of increase prism, improves the utilization rate of scanning angle and the utilization rate of motor.However, from
The axiality of the reflex prism of main processing tends not to be completely secured, if three prism facets of reflex prism are all carried out simultaneously
Scanning, will appear from the deviation of scan vision, thus, to ensure the axiality of scanning field of view, selection only utilizes one of prism
Face is scanned.In conjunction with view of dimensional problem, selection reflex prism.
On the basis of above-mentioned technical proposal, further, sounding optical system can also include collimated light scholar
