Imaging head with pigtailed laser diodes and micromachined light-pipe and arrays thereof

摘要

An optical imaging heads that produce a plurality of light spots on light sensitive medium such as photographic film or printing plate. The optical head incorporates an array of multi-mode laser diodes optically coupled to multi-mode optical fibers, an array of micromachined supports for the optical fibers, an array of micromachined light-pipes (MLPs) aligned with the supports and with the optical fibers and means for imaging the exit aperture of each of the micromachined light-pipes on a photosensitive medium.
