Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As Figure 1-4, a kind of double mode camera module, including imaging unit 1 and it is arranged on entering for the imaging unit 1
Rotatable reflecting prism 2 on light direction, the light of object are projected to the imaging after the reflecting prism 2 reflection
It is imaged on unit 1；The reflecting prism 2 includes being used for first plane of incidence 21 and second plane of incidence 22, the use that light is injected
In light project the first exit facet 23 and the second exit facet 24 and for light reflection the first reflecting surface 25 and second it is anti-
Penetrate face 26；Wherein, in first plane of incidence 21, second plane of incidence 22, the first exit facet 23 and the second exit facet 24 wherein
Infrared absorption filter photosphere 4 is provided with simultaneously.
As shown in figs. 1 and 3, before rotation, its first plane of incidence 21 is emitted the reflecting prism 2 towards object, first
Face 23 is injected towards the imaging unit 1, light from first plane of incidence 21, after first reflecting surface 25 reflection,
Projected from first exit facet 23；As shown in Figures 2 and 4, the reflecting prism 2 after rotation, its direction of second plane of incidence 22
Object, the second exit facet 24 is towards the imaging unit 1, and light is injected from second plane of incidence 22, by described second
After reflecting surface 26 reflects, projected from second exit facet 24.
The double mode camera module enters on light direction to be provided with rotatable reflecting prism 2 the imaging unit 1, leads to
Cross and rotate the reflecting prism 2, switch the reflecting prism 2 towards the plane of incidence of object and towards the imaging unit 1
Exit facet, and the wherein one side in first plane of incidence 21, second plane of incidence 22, the first exit facet 23 and the second exit facet 24
On be provided with infrared absorption filter photosphere 4, i.e., described reflecting prism 2 allows the light type that passes through different before and after rotation, and can be achieved can
See the double mode switching of light and infrared light.
If light is in communication process without the infrared absorption filter photosphere 4, then, it is seen that in light transmission to the imaging unit 1
It is imaged, obtains visible images；If light passes through the infrared absorption filter photosphere 4 in communication process, then, it is seen that light is described
