LIQUID CRYSTAL FOR VISION CORRECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240319503 titled 'LIQUID CRYSTAL FOR VISION CORRECTION

The patent application discusses an optical system, a head-mounted display (HMD) system, and a method for tuning the optical system. The optical system includes liquid crystal lenses with chromatic aberrations, as well as a Pancharatnam-Berry (PB) phase lens with complementary chromatic aberrations. The HMD system consists of a display device, the optical system, and a virtual reality (VR) viewing optical system.

• The optical system features liquid crystal lenses with chromatic aberrations.
• A PB phase lens with complementary chromatic aberrations is included in the optical system.
• The HMD system comprises a display device, the optical system, and a VR viewing optical system.

Potential Applications: - Virtual reality gaming - Augmented reality applications - Medical imaging technology
