Description

A kind of continuous scanning means of multi-angle
Technical field
It the utility model is related to detecting devices technical field, more particularly to a kind of continuous scanning means of multi-angle.
Background technology
At present, obtained in spatial information and industrial navigation field, the scanning means scan mode for target acquisition are main There are oscillatory type scanning, the scanning of rotating prism formula and spiral scan, oscillatory type scanning and the scanning of rotating prism formula are only single Scanning angle, and spiral scan is poor in the information obtaining ability of scanning means axis direction.In industrial navigation field, generally To the directional demand of information collecting capacity of sensor, and require that the acquisition scope of spatial information is big, traditional scanning dress Put and obvious limitation be present on technology is applied.
The content of the invention
The purpose of this utility model is to provide a kind of continuous scanning means of multi-angle, and abundant, covering is pointed in device scanning Angular region is bigger, so as to expand investigative range, it is widely used in a variety of industrial navigation fields.
A kind of continuous scanning means of multi-angle, described device include polygon scanner and scan axis, wherein:
The polygon scanner includes multiple scan mirrors, and each scan mirror rotates around the scan axis;
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.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme of the utility model embodiment The accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some implementations of the present utility model Example, on the premise of not paying creative work, can also be according to these accompanying drawings for one of ordinary skill in the art Obtain other accompanying drawings.
The structural representation for the continuous scanning means of multi-angle that Fig. 1 is provided by the utility model embodiment;
Fig. 2 is another structural representation of polygon scanner described in the utility model embodiment;
Fig. 3 is another structural representation of polygon scanner described in the utility model embodiment;
Angles of the Fig. 4 between each scan mirror described in the utility model embodiment sets identical structural representation;
Angles of the Fig. 5 between each scan mirror is arranged to the structural representation differed.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear Chu, it is fully described by, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made The every other embodiment obtained, belongs to the scope of protection of the utility model.
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 46°。
In addition, the angle between each scan mirror of the polygon scanner can be arranged to it is identical or different, such as Fig. 4 institutes The angle being shown as between each scan mirror described in the utility model embodiment sets identical structural representation, as shown in Figure 5 Angle between each scan mirror is arranged to the structural representation differed.
In summary, the device scanning that the utility model embodiment is provided, which is pointed to, to be enriched, and covering angular region is bigger, so as to Investigative range is expanded, it is widely used in a variety of industrial navigation fields.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should It is defined by the protection domain of claims.
