Zusammenfassung: | Disclosed are an optical system of a head mounted display and a head mounted display with same. The optical system, according to one disclosed embodiment, comprises: a display panel for generating image light; a reflective polarizing plate for reflecting one polarized component among polarized components of the image light; a convex curved mirror for enlarging the image light reflected from the reflective polarizing plate, and reflecting same toward the reflective polarizing plate; a phase shift film disposed between the reflective polarizing plate and the convex curved mirror so as to change the direction of polarization of the image light; an incident lens for collimating the image light which has been reflected from the convex curved mirror and transmitted through the reflective polarizing plate; and a waveguide having the light, collimated by the incident lens, incident thereon, and emitting the incident image light toward an eye of a user.
Système optique d'un dispositif d'affichage monté sur la tête et dispositif d'affichage monté sur la tête pourvu de celui-ci. Le système optique, selon un mode de réalisation décrit, comprend : un panneau d'affichage pour générer une lumière d'image ; une plaque de polarisation réfléchissante pour réfléchir une composante polarisée parmi des composantes polarisées de la lumière d'image ; un miroir incurvé convexe pour agrandir la lumière d'image réfléchie depuis la plaque de polarisation réfléchissante, et réfléchir celle-ci vers la plaque de polarisation réfléchissante ; un film de déphasage disposé entre la plaque de polarisation réfléchissante et le miroir incurvé convexe de façon à changer la direction de polarisation de la lumière d'image ; une lentille d'incidence pour collimater la lumière d'image qui a été réfléchie depuis le miroir incurvé convexe et transmise à travers la plaque de polarisation réfléchissante ; et un guide d'ondes ayant la lumière, collimatée par la lentille incidente, incident sur celui-ci, et émettant la lumière d'image incidente vers un œil d'un utilisateur.
