摘要：
In part, the invention relates to a lens assembly. The lens assembly includes a micro-lens； a beam director in optical communication with the micro-lens； and a substantially transparent film. The substantially transparent film is capable of bi-directionally transmitting light, and generating a controlled amount of backscatter. In addition, the film surrounds a portion of the beam director.
