Multiple wire system laser radar at present, optical emission system, which mainly has, to be realized using multiple alignment lasers in one-dimensional square
Arrangement upwards, then be driven by a motor integral-rotation and form 360 degree of scannings, such as patent CN107121683A, the master of this mode
It wants to be unfavorable for the miniaturization of product the disadvantage is that the volume difficulty of multiple alignment lasers is done small, generally for arranging in a limited space
The more alignment lasers of cloth need to increase optical path debugging difficulty using multiple reflecting mirrors, the number of scanning lines that usually may be implemented
Also fewer.
Another kind realizes the mode that laser beam scans in one-dimensional direction, such as patent using MEMS galvanometer scheme
CN107422473A.This scheme main problem is very to rely on the performance of MEMS galvanometer, and speed is measured on vibration mirror scanning direction
Degree would generally be slow compared with other modes, and in addition current MEMS galvanometer technique is not mature enough, and service life is also a problem.
For another example patent CN205749898U carries out collimation transmitting using lens group, in this way will to laser light source beam divergence angle
Ask higher.Beam divergence angle is too big usually on fast axis direction for LD light source, and Gaussian Profile is poor, and directly and lens group coupling efficiency is very low.
If usual peak power is lower using VCSEL light source.And the limited package size with laser light source influences, in limited picture
The quantity of light source that can be arranged in the size of face is limited, is difficult to realize intensive line number.In addition its light source is placed in a cambered surface, is increased
