A method for switching signals using one of a plurality of mirrors in an array structure. The method includes determining an optical path to be formed between an input fiber and an output fiber. The method also includes determining a set of mirrors to be used to form the optical path. The set of mirrors includes at least a first mirror. The first mirror is coupled to a mechanical spring assembly and an actuation assembly. The method captures an analog signal indicative of a spatial position of the first mirror using a position sensing device. The sensing device is coupled to the mirror. The method also converts the signal analog signal into a digital signal. The method processes the digital signal indicative of the spatial position of the mirror using the digital signal processing device to obtain a characteristic of the mirror. The method provides a control signal based upon the characteristic of the mirror. The converts the control signal into an analog control signal. The method uses the analog control signal with the actuation assembly to set a desired position of the first mirror.
