Abstract
A micro-electro-mechanical system (MEMS) device includes a mirror; at least one hinge; an electrostatic comb structure; and a control device. The control device causes, for a period of time, a voltage to be supplied to the electrostatic comb structure to cause the electrostatic comb structure to tilt the mirror about the at least one hinge in a particular direction. The control device causes, after the period of time and at an instant of time, the voltage to cease being supplied to the electrostatic comb structure. A tilt angle of the mirror, at the first instant of time, is less than a maximum tilt angle of the mirror in the particular direction. An angular momentum of the mirror, at the instant of time, is greater than zero kilogram meters squared per second in the particular direction.
