Embodiment Construction
[0034] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0035] An embodiment of the present invention provides a polarization imaging device, such as figure 1 and figure 2 As shown, the polarization imaging device includes:
[0036] image sensor 10;
[0037] The liquid crystal lens 20 is arranged between the target object 1 to be imaged and the image sensor 10. The liquid crystal lens 20 includes at least three layers of liquid crystal layers parallel to each other, an electrode layer and an alignment layer adapted to each liquid crystal layer, each One layer of liquid crystal layer corresponds to the orientation angle of an orientation layer, and each orientation angle is different from each other; in addition, the liquid crystal lens 20 also includes a voltage drive circuit, and each e...
