Abstract: A method for making a microlens comprising the steps of uniformly distributing a volume of Poly(methylmethacrylate) (PMMA) across a major surface of a substrate, hardening the PMMA layer on the substrate surface, patterning the PMMA layer and forming patterned PMMA and reflowing the patterned PMMA to form at least one microlens on the substrate.

Abstract: An apparatus for creating an illusion of eye contact in a video telephony system includes a video camera and a display screen. The video camera is aligned with the display screen so the viewer's image is transmitted by the video camera with the illusion of eye contact. The display screen has an array of lenses defining part of a first optical path, for transmitting to a video camera a viewer's image. An array of regions interspersed among the array of lenses defines part of a second optical path, for directing to the viewer, displayed images. The array of lenses and the array of regions are each too small to be separately resolvable by the human eye, so that the lenses do not interfere with the perceived quality of the transmitted viewer's image, and the transparent regions do not deteriorate noticeably the video display images projected to the viewer.
