Abstract
A reflector array optical device includes two dihedral corner reflector array optical elements each having a substrate and a plurality of prism bodies arranged regularly on and each protruding from one main surface of the substrate. Each prism body includes at least two sides of orthogonal planes. The two optical elements are adhered so that top faces of the prism bodies are directly confronted respectively so as to make two coplanar planes in which the two orthogonal planes exist respectively.
