Abstract
Aspects of the disclosure provide an optical system, a head mounted display (HMD) system, and a method of tuning the optical system. The optical system can include one or more liquid crystal (LC) lenses that are refractive optical elements. The one or more liquid crystal lenses can have a first chromatic aberration. The optical system can include a Pancharatnam-Berry (PB) phase lens that is a diffractive optical element. The PB phase lens can have a second chromatic aberration that is complementary to the first chromatic aberration. A chromatic aberration of the optical system can be less than the first chromatic aberration. The HMD system can include a display device, the optical system, and a virtual reality (VR) viewing optical system.
