Abstract
The present invention provides a method of testing micro-electrical mechanical mirrors including simultaneously applying a voltage to each of a plurality of such mirrors to tilt each of the plurality to a deflection angle, and simultaneously deflecting a beam from each of the plurality using an interferometer to simultaneously determine an accuracy of the deflection angle of each of the plurality. In addition, a method of manufacturing micro-electrical mechanical mirrors is also disclosed.
