Abstract

An electrically tunable LCOS pico projector using a liquid crystal (LC) lens as an active optical element is demonstrated. The LC lens consists of two built-in sub-lenses: one is an electrically tunable focusing lens controlled by a LC layer and the other is a fixed focused polymeric lens. The tunable ranges of the electrically tunable LCOS pico projectors are 200 cm to ∼7 cm. The driving voltage of the electrically tunable focusing LCOS pico projector is less than 35 V rms. The response times is 1.1 sec. The image performance of the electrically tunable focusing LCOS pico projector is also demonstrated.
