WIPO Patent Application WO/2018/042830
Kind Code:
A1
Abstract:
Provided is an optical imaging apparatus in which the brightness of a virtual image is high and which can be easily manufactured at low cost. The optical imaging apparatus is mainly formed of: a polarizer 2 that transmits P-polarized light and reflects S-polarized light; a phase difference element 3 that converts one or both of the P-polarized light transmitted through the polarizer 2 and the S-polarized light reflected by the polarizer 2 into circularly polarized light or elliptically polarized light; and a retroreflection element 4 that retroreflects the light having passed through the phase difference element 3.
