A simple view control mechanism is developed and applied to a virtual learning environment for the refraction of light. The view control function is linked to body movement. A learner's observing position and direction are concurrently chased and then the visual information of an observed object is displayed on a head mounted display. The behavior of light… (More)
An optical triplexer with cascaded multi-mode interference (MMI) couplers is proposed in an optical access system. The optical triplexer is constructed on a silicon-on-insulator (SOI) substrate. The optical triplexer was designed by use of beam propagation method.
