A holographic polymer dispersed liquid crystal (H-PDLC) switchable lens is reported. The diffraction efficiency was analyzed at different phase separation coefficients within the visible band (400—800 nm) with the coupled wave theory for a phase-type H-PDLC switchable lens. In our experiments, the maximum efficency of 70% was achieved. The H-PDLC switchable lens shows excellent imaging performance and fast response.It is potentially useful in many applications, such as optical communications, optical imaging,e.g.,in digital cameras.
