Abstract
A device has a waveguide, such as monomode fiber, for receiving a light beam and retransmitting specific portions of the light in a reemitted beam, which reemitted beam can be moved in space. To move the reemitted beam, the device has an arrangement for moving an end portion of the light waveguide adjacent the outlet surface to change the direction of the reemitted beam. The waveguide, such as the cladded optical fiber, can be either provided with a mode stripper or is of a sufficient length so that cladding modes will be eliminated before reaching the outlet surface. To move the end of the waveguide, various arrangements, which can utilize either an electro-magnet, a piezoelectric device or other suitable movement devices, are utilized. The device usually includes outlet optics for the reemitted beam and these optics can either be a gradient lens secured on the outlet surface of the waveguide or a lens which is spaced a distance from the outlet surface.
