Abstract
A polarization imaging image-pickup system includes an image-pickup unit array that includes a plurality of image-pickup units arranged two-dimensionally, wherein the image-pickup units each include: one wavefront control element that includes a plurality of microscopic structures; and a pixel array that is arranged so as to face the wavefront control element, and includes a plurality of pixels that are associated with the wavefront control element and are two-dimensionally arranged, and light from an imaging object is spatially separated by the one wavefront control element into first polarized light, and a second polarized light that is in a direction orthogonal to the first polarized light or has a rotation direction opposite to a rotation direction of the first polarized light, the first polarized light is collected at a first collection position on the pixel array, and the second polarized light is collected at a second collection position on the pixel array.
