Fig. 3 show the light path schematic diagram of the laser radar of the utility model embodiment, as shown in figure 3, laser radar
Optical system includes receiving optical unit 310, further includes speculum 320.
Speculum 320, which is arranged at, to be received between optical unit 310 and receiver 330, for adjusting the light path side of reflected light
To.
The optical path direction that speculum 320 is used to adjust reflected light includes：
Speculum 320 is used for the photosurface by the reflected light back to the receiver 330.
After launching light by launching optical unit 340, reflected by target object 350, transmitting light is by receiving optical unit
After 310, speculum 320 adjusts the light path of reflected light, reflected light is launched to the photosurface of receiver 330.
In the utility model embodiment, laser radar includes a speculum, which can adjust the light of reflected light
Road direction, by the photosurface of reflected light back to receiver, the laser radar for being provided with speculum is either detecting closely
Target object, or detection distant object object, reflected light can be received by the photosurface of receiver, can not increased
Remote detection is realized in the case of photosurface area and is closely detected, and since the cost of speculum is low, it is small, therefore
Laser radar it is small, cost is low.
