Abstract
The present disclosure generally relates to a method, and apparatus implementing the method for removing particulate accumulation from an optical element of a micro electromechanical systems (MEMS) package. The method may select a cleaning mode based, at least in part on, one or more of output of a sensor or a maintenance routine. Cleaning modes may include actuating, using an actuator of the MEMS package, one of a plurality of motion modes across the optical element. Optionally, the cleaning mode may include applying, using a power source of the MEMS package, a charge to the optical element. The disclosed techniques may enable the MEMS package to automatically and dynamically remove particulate matter without introducing additional mechanical elements.
