Lens module 100 according to an embodiment of the present invention, as shown in Figure 3 and Figure 4, comprising: a plurality of lenses 1, reflection microscope group
Part 2 and multiple images sensor 3.
A plurality of lenses 1 are circumferentially arranged in a ring, and each camera lens 1 all has outer end a and inner end b, the inner end of a plurality of lenses 1
B circular region is center region Q, and mirror assembly 2 is located in the Q of central area.Here, for convenience of description, it is assumed that camera lens mould
Group 100 has center line L, and the center line L of 1 surrounding lens mould group 100 of a plurality of lenses arranges, around center in following discussion
The direction that the direction of line L is known as circumferentially being parallel to center line L is known as axially.The inner end b of each camera lens 1 refers to the court of camera lens 1
To one end of center line L, the outer end a of each camera lens 1 refers to one end of the separate center line L of camera lens 1, during center line L is located at
The center position of heart district domain Q.
At least one in multiple images sensor 3 is located at outside the Q of central area, multiple images sensor 3 and a plurality of lenses 1 one
One is correspondingly arranged, and each imaging sensor 3 receives the light that corresponding camera lens 1 is reflected through mirror assembly 2.
That is, the corresponding each camera lens 1 of mirror assembly 2 is equipped with reflecting surface.For each camera lens 1, light is logical
The outer end a for crossing camera lens 1 is injected, and is projected after then being reflected by camera lens 1 from the inner end b of camera lens 1, and on directive mirror assembly 2
