Abstract:
A method for switching signals using one of a plurality of mirrors in an array structure, the method comprising:determining an optical path to be formed between an input fiber and an output fiber; determining a set of mirrors to be used to form the optical path, the set of mirrors including at least a first mirror, the first mirror being coupled to a mechanical spring assembly, and an actuation assembly; capturing an analog signal indicative of a spatial position of the first mirror using a position sensing device, the sensing device being coupled to the mirror; converting the signal analog signal into a digital signal; processing the digital signal indicative of the spatial position of the mirror using the digital signal processing device to obtain a characteristic of the mirror; and providing a control signal based upon the characteristic of the mirror; converting the control signal into an analog control signal; and using the analog control signal with the actuation assembly to set a desired position of the first mirror.
