Abstract: An imaging system that includes a first polarization structure that polarizes light provided from a light source into first polarized light, a first power supply connected to the first polarization structure and that applies a first voltage to the first polarization structure, a meta-lens on which the first polarized light is incident, a second polarization structure that converts the first polarized light that passes through the meta-lens into second polarized light, a second power supply connected to the second polarization structure and that applies a second voltage to the second polarization structure, and an image sensor that senses the second polarized light. The first voltage and the second voltage are different from each other.
