33‐4: Fast Switchable Multi‐Focus Polarization‐Dependent Ferroelectric Liquid‐Crystal Lenses for Virtual Reality

In this paper, we propose a fast switchable lens system with multiple focal points. Specifically, the combination of the Electrically Suppressed Helix Ferroelectric Liquid Crystal (ESHFLC) based polarization rotator and a passive polarization‐dependent LC lens can switch the focal points at high spe...

Description
Summary:In this paper, we propose a fast switchable lens system with multiple focal points. Specifically, the combination of the Electrically Suppressed Helix Ferroelectric Liquid Crystal (ESHFLC) based polarization rotator and a passive polarization‐dependent LC lens can switch the focal points at high speed (50µs). Moreover, a cascaded assembly of 3 such lens units shows 8‐focal points, with a fast response time of 50µs. This device shows promising potential for VR and depth‐mapping.
