20130128005 | TWO-PARALLEL-CHANNEL REFLECTOR WITH FOCAL LENGTH AND DISPARITY CONTROL - A two-parallel-channel reflector (TPCR) with focal length and disparity control is used after being combined with an imaging device. A left parallel channel and a right parallel channel are formed in the TPCR, so that the imaging device can synchronously perform an imaging operation on a left side view and a right side view of a scene, so as to obtain a stereoscopic image. Each parallel channel is bounded by two curved reflecting mirrors, so that captured light rays may be parallelly reflected in the channel, and an operator may adjust a convergence angle and an interocular distance between the left side view and the right side view, so as to control the focal length and disparity during imaging as require. | 05-23-2013 |
