This paper investigates the technique of optical actuation of MEMS. It is shown that a device can be driven into all of its vibrational modes simply and non-destructively by a laser pulse, making this an ideal actuation methodology for device characterization at the wafer level. This actuation method is shown to be comparable to a mechanical impulse actuation.
