Title:
OPTICAL IMAGING SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/020399
Kind Code:
A1
Abstract:
An optical imaging system and a control method, which are used to eliminate stray light produced during a light beam state adjustment process. A control assembly (200) controls a state regulation assembly (110) to perform light beam state regulation on inputted polarized light, so as to output target polarized light and stray polarized light, the polarization direction of the stray polarized light being orthogonal to that of the target polarized light; and then a stray polarized light elimination assembly (120) is controlled according to the polarization direction of the stray polarized light, such that the stray polarized light elimination assembly (120) adjusts the polarization direction of the stray polarized light under the control of the control assembly (200), so as to eliminate the stray polarized light and output the target polarized light. The optical imaging system and the control method are used to eliminate stray light produced by a multi-state display system.
