Abstract:
(EN) An optical architecture of a liquid crystal optical projection device (3) and a beam processing method therefor. The method comprises: identifying and classifying unpolarized incident light beams (B1) into a first light beam in a first polarization direction and a second light beam in a second polarization direction; deflecting the first light beam, and identifying and classifying the deflected first light beam as a third light beam in the first polarization direction and a fourth light beam in the second polarization direction; recovering the second light beam and the fourth light beam, and performing photoelectric conversion; and sending the third light beam to a projector lens (36). The energy of the second and fourth light beams in the second polarization direction that are not used by the liquid crystal optical projection device (3) for displaying is photo-electrically converted into electric energy to be stored, so as to avoid waste of the energy of the second and fourth light beams.
(FR) L'invention concerne une architecture optique d'un dispositif de projection optique à cristaux liquides (3) et un procédé de traitement de faisceaux associé. Le procédé consiste à : identifier et classifier des faisceaux lumineux incidents non polarisés (B1) en premier faisceau lumineux dans une première direction de polarisation et deuxième faisceau lumineux dans une seconde direction de polarisation ; dévier le premier faisceau lumineux, et identifier et classifier le premier faisceau lumineux dévié en tant que troisième faisceau lumineux dans la première direction de polarisation et quatrième faisceau lumineux dans la seconde direction de polarisation ; récupérer le deuxième faisceau lumineux et le quatrième faisceau lumineux, et réaliser une conversion photoélectrique ; et envoyer le troisième faisceau lumineux vers une lentille de projecteur (36). L'énergie des deuxième et quatrième faisceaux lumineux dans la seconde direction de polarisation qui ne sont pas utilisés par le dispositif de projection optique à cristaux liquides (3) pour l'affichage est convertie photoélectriquement en énergie électrique à accumuler, de façon à éviter la perte de l'énergie des deuxième et quatrième faisceaux lumineux.
(ZH) 一种液晶光学投影装置(3)的光学架构与其光束处理方法,该方法包括:分辨未极化的入射光束(B1)为第一极化方向的第一光束与第二极化方向的第二光束;对第一光束进行偏转处理,并分辨偏转后的第一光束为第一极化方向的第三光束与第二极化方向的第四光束;回收第二光束与第四光束,并进行光电转换;以及将第三光束送至投影机镜片(36)。将未被液晶光学投影装置(3)用于显示的第二极化方向的第二与第四光束的能量通过光电转换为电能而被储存,从而不会有浪费第二与第四光束的能量的问题。
