Title (EN) OPTICAL IMAGING APPARATUS
(FR) APPAREIL D'IMAGERIE OPTIQUE
(JA) 光結像装置
Abstract:
(EN) 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.
(FR) La présente invention concerne un appareil d'imagerie optique dans lequel la luminosité d'une image virtuelle est augmentée et pouvant être facilement fabriqué à faible coût. L'appareil d'imagerie optique est principalement constitué : d'un polariseur (2) qui émet une lumière polarisée P et réfléchit une lumière polarisée S ; un élément de différence de phase (3) qui convertit une ou les deux lumières polarisées P émises à travers le polariseur (2) et la lumière polarisée S réfléchie par le polariseur (2) en une lumière polarisée de manière circulaire ou une lumière polarisée elliptique ; et un élément de rétroréflexion (4) qui rétroréfléchit la lumière ayant traversé l'élément de différence de phase.
(JA) 虚像の明度が高く、製造が簡単で低コストな光結像装置を提供する。P偏光を透過し、S偏光を反射する偏光子2と、偏光子2を透過したP偏光および偏光子2で反射したS偏光のいずれか一方又は両方を円偏光又は楕円偏光に変換する位相差素子3と、位相差素子3を通過した光を再帰反射させる再帰反射素子4と、で主に構成される。
