Abstract:
1. A method for controlling a micro-electromechanical system (MEMS), said method comprising: providing a plurality of rotatable mirrors to form a MEMS array, wherein each of said plurality of rotatable mirrors includes an associated optical sensor; supplying electrical potential to each of said plurality of optical sensors, wherein each one of said plurality of optical sensors is configured to provide a variable range of voltages to an associated rotatable mirror; directing an optical control beam onto a first optical sensor, which is one of said plurality of optical sensors, wherein said first optical sensor determines optical characteristics of said optical control beam; responsively supplying voltage to a rotatable mirror that is associated with said first optical sensor, wherein an amount of said supplied voltage is based on the determined optical characteristics of said optical control beam; and rotating said rotatable mirror that is associated with said first optical sensor about a primary axis in response to said supplied voltage.
