A light beam scanner comprises a light source providing a beam of light and a microelectromechanical systems (MEMS) scanning mirror that reflects the beam of light through a light-transmissive window. A light detector receives the light that is reflected off a target and that passes back through the light-transmissive window. The MEMS scanning mirror oscillates to provide a scan pattern to the beam of light. The MEMS scanning mirror comprises a resonate transducer in order to oscillate the reflective surface to provide a desired scan pattern.

[ What is claimed is:] [1.] A light beam scanner, comprising:a light source providing a beam of light;a MEMS mirror spaced from said light source and having a reflective surface that reflects said beam of light, said MEMS mirror comprising a resonant transducer that oscillates;a partially-reflective mirror disposed between said light source and said MEMS mirror, said partially-reflective mirror permitting said beam of light to pass therethrough and travel from said light source to said MEMS mirror, said partially-reflective mirror substantially reflecting any reflected light returning from said MEMS mirror towards said light source; anda light detector spaced from said partially-reflective mirror to receive said reflected light from said partially-reflective mirror.
