1. An optical system comprising:
- a first optical member having a concave surface that reflects a light having a first circularly polarized light component and transmits a light having a second circularly polarized light component a rotation direction of which is opposite to a rotation direction of the first circularly polarized light component; and
a second optical member that transforms the light having the first circularly polarized light component reflected from the first optical member into the light having the second circularly polarized light component to be reflected so as to be incident on the first optical member.

Abstract
An optical system includes: a first optical member having a concave surface that reflects a light having a first circularly polarized light component and transmits a light having a second circularly polarized light component a rotation direction of which is opposite to a rotation direction of the first circularly polarized light component; and a second optical member that transforms the light having the first circularly polarized light component reflected from the first optical member into the light having the second circularly polarized light component to be reflected so as to be incident on the first optical member.

10. An optical member comprising:
-
a reflective linear polarizer plate that transmits a first linearly polarized light component and reflects a second linearly polarized light component which is orthogonal to the first linearly polarized light; a quarter-wave plate that is arranged facing one surface of the reflective linear polarizer plate; and a reflective mirror that has a concave surface facing the quarter-wave plate and reflects a first circularly polarized light component having a rotation direction corresponding to the first linearly polarized light component incident on the concave surface and transmits a second circularly polarized light component having a rotation direction opposite to a rotation direction of the first circularly polarized light component. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
