Abstract:
(EN) An optical architecture of a liquid crystal optical projection device and a beam processing method therefor. The method comprises: identifying and classifying unpolarized incident light beams into a first light beam in a first polarization direction and a second light beam in a second polarization direction (S51); deflecting the first light beam and the second light beam, and merging the deflected first light beam and second light beam, wherein the sum of the deflection angle of the first light beam and the deflection angle of the second light beam is 90 degrees (S52); identifying and classifying the merged first light beam and second light beam into a third light beam in the first polarization direction and a four light beam in the second polarization direction (S53); and sending the third light beam to a projector lens (S54).
(FR) L'invention concerne une architecture optique d'un dispositif de projection optique à cristaux liquides et un procédé de traitement de faisceaux associé. Le procédé consiste à : identifier et classifier des faisceaux lumineux incidents non polarisés en un premier faisceau lumineux dans une première direction de polarisation et en un deuxième faisceau lumineux dans une seconde direction de polarisation (S51) ; dévier le premier faisceau lumineux et le deuxième faisceau lumineux, et fusionner le premier faisceau lumineux et le deuxième faisceau lumineux déviés, la somme de l'angle de déviation du premier faisceau lumineux et de l'angle de déviation du deuxième faisceau lumineux étant de 90 degrés (S52) ; identifier et classifier le premier faisceau lumineux et le deuxième faisceau lumineux fusionnés en un troisième faisceau lumineux dans la première direction de polarisation et en un quatrième faisceau lumineux dans la seconde direction de polarisation (S53) ; et envoyer le troisième faisceau lumineux vers une lentille de projecteur (S54).
(ZH) 一种液晶光学投影装置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为第一极化方向的第一光束与第二极化方向的第二光束(S51);对第一光束与第二光束进行偏转处理,并合并偏转后的第一光束与第二光束,其中第一光束的偏转角度与第二光束的偏转角度的总和为90度(S52);分辨合并的第一光束与第二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(S53);以及将第三光束送至投影机镜片(S54)。
