Document Type and Number:
WIPO Patent Application WO/2022/252724
Kind Code:
A1
Abstract:
An optical system, an illumination system, and a display system. The optical system at least comprises a light source assembly (10), a light adjustment assembly (20), a first polarization beam splitter assembly (30), a first lens assembly (41) and a second lens assembly (42), wherein the light source assembly (10) is used for generating a light beam including S-polarized light and P-polarized light; the light adjustment assembly (20) is used for adjusting the proportion of the S-polarized light and the proportion of the P-polarized light in the light beam; the first polarization beam splitter assembly (30) is used for splitting the light beam adjusted by the light adjustment assembly (20) into a first light beam and a second light beam, the first light beam being a light beam of the S-polarized light, and the second light beam being a light beam of the P-polarized light; the first lens assembly (41) is used for projecting the first light beam or the modulated first light beam to a first region; and the second lens assembly (42) is used for projecting the second light beam or the modulated second light beam to a second region. Dynamic adjustment of the beam splitting ratio of a multi-mirror optical system is realized.
