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 optical-fiber 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 micromechanical mirrors (e. g. MEMS mirrors) operated in arrays or singly, liquid-crystal devices, and other controlled-birefringence cells. Some of these devices are placed within an optical system for directional light-beam steering.
