Abstract
The present disclosure is directed to compact packaging for optical MEMS devices, such as one- and two-dimensional beam scanners. An embodiment in accordance with the present disclosure includes a light source and a MEMS-based scanning element for steering at least a portion of the light provided by the light source in at least one dimension as an output light signal, as well as one or more optical elements for collimating and/or redirecting light within a sealed chamber defined by the elements of a housing. In some embodiments, the one or more optical elements include a reflective lens that collimates the light provided by the light source while simultaneously correcting phase-front error imparted by the scanning element while steering the output beam.
