Open the CIPO recordAbstract From the Canadian patent
Several systems and a method are taught for rapid modulation of a light beam in lidar and other imaging. Most of these involve micromechanical and other very small control components. One such unit is a light-switching fabric based on displacement of liquid in a tube that crosses a junction of two optical waveguides. In some forms, the fabric is preferably flexible to enable folding or coiling to form a two-dimensional face that interacts with opticalfiber ends an opposed fiber bundle. The rapid operation of the switch fabric enables it to be used as a beam-splitter separating incoming and return , beams; and also to form pulses from supplied CW light. Other control components include …

Why it's free to use
- Filed May 16, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 16, 2023.
