APPARATUS, METHOD, AND COMPUTER PROGRAM PRODUCT FOR TESTING WAVEGUIDED DISPLAY SYSTEM AND COMPONENTS

摘要

An apparatus and method for a waveguided switching matrix. A method of operating the switching matrix including a plurality of arranged waveguides each having an associated influencer structure for independently influencing an amplitude-effecting attribute of radiation propagating through a corresponding waveguide wherein the attribute includes a first mode for an "OFF" propagation mode with an exit amplitude substantially extinguished level and a second mode for an "ON" propagation mode with the exit amplitude at a substantially fully illuminated level, includes: a) establishing an "OFF" characteristic for the amplitude-effecting attribute to set the first mode; b) setting an "ON" characteristic for the amplitude-effecting attribute that does not match the second mode and establishes an intermediate propagation mode between the OFF propagation mode and the ON propagation mode; and c) adjusting a second attribute of radiation propagating through the waveguide so that the exit amplitude in the intermediate propagation mode substantially equals the fully illuminated level.
