The normal of each scan mirror is from the scan axis respectively into different space angles.
Each scan mirror is uniformly distributed around the scan axis.
Each scan mirror surrounds the scan axis non-uniform Distribution.
The polygon scanner is rectangular parallelepiped space structure, and each scan mirror is divided with the corresponding angle of the scan axis
It is not 91 °, 90 °, 89 ° and 88 °.
The polygon scanner is prism space structure, and each scan mirror is distinguished with the corresponding angle of the scan axis
It is 92 °, 91 °, 90 °, 89 ° and 88 °.
The polygon scanner is terrace with edge space structure, and each scan mirror is distinguished with the corresponding angle of the scan axis
It is 43 °, 44 °, 45 ° and 46 °.
Angle between each scan mirror of the polygon scanner is arranged to identical or different.
Abundant, cone of coverage model is pointed in said apparatus scanning it can be seen from above-mentioned technical scheme provided by the utility model
Enclose more greatly, so as to expand investigative range, it is widely used in a variety of industrial navigation fields.

The utility model embodiment is described in further detail below in conjunction with accompanying drawing, is as shown in Figure 1 this practicality
The structural representation for the continuous scanning means of multi-angle that new embodiment is provided, described device include polygon scanner and scanning
Axle, with reference to figure 1:
The polygon scanner includes multiple scan mirrors 2, and each scan mirror 2 rotates around the scan axis 1, to realize
Optical mechaical scanning;
The normal 3 of each scan mirror 2 is from the scan axis 1 respectively into different space angles 4;
For same laser beam 5, the sensing that each scan mirror 2 produces reflected light is different, when each scanning mirror
Face 2 around the scan axis 1 rotate when, the corresponding sweep trace 6 for producing different spaces distribution.
In the specific implementation, each scan mirror can be uniformly distributed around the scan axis, i.e., each adjacent scan mirror
Projected angle of two normals on scan axis sagittal plane is equal.
Or each scan mirror surrounds the scan axis non-uniform Distribution, i.e., two normals of each adjacent scan mirror
Projected angle on scan axis sagittal plane can not wait.
In addition, as shown in figure 1, the polygon scanner is rectangular parallelepiped space structure, and each scan mirror 2 and the scanning
The corresponding angle of axle 1 is 91 °, 90 °, 89 ° and 88 ° respectively.
The polygon scanner can also be arranged to other space structures, be illustrated in figure 2 described in the utility model embodiment
Another structural representation of polygon scanner, the polygon scanner are arranged to prism space structure, and each scan mirror and institute
The corresponding angle for stating scan axis is 92 °, 91 °, 90 °, 89 ° and 88 ° respectively.
Another structural representation of polygon scanner described in the utility model embodiment is illustrated in figure 3, more Surface scans
Mirror is arranged to terrace with edge space structure, and each scan mirror and the corresponding angle of the scan axis be respectively 43 °, 44 °, 45 ° and
