ABSTRACT:
A compact lightweight display system which can be used as a collimating eyepiece is provided. The system utilizes a cholesteric liquid crystal device in combination with an optical doublet. A partially reflective coating is at the interface between the two singlets which comprise the doublet. The design of this system reduces the number of element to air and/or element to element interfaces, thus reducing losses and ghosting while making a sturdier, more vibration tolerant display system.
