Abstract: An optical device is disclosed. The optical device includes a plurality of reflective pillars extending in a first direction, and the plurality of reflective pillars are arranged in a plurality of rows and a plurality of columns. The first direction is perpendicular to both a row direction and a column direction. Every at least three adjacent reflective pillars define an optical channel extending in the first direction. Each optical channel includes a plurality of reflective surfaces arranged in a circumferential direction of the optical channel, and the plurality of reflective surfaces include two reflective surfaces that are adjacent and perpendicular to each other. A plurality of reflective surfaces defining the optical channel are respectively located on different reflective pillars.
