ABSTRACT:
A pair of directing elements directs a beam of light into a corresponding optical output from a corresponding optical input. Examples of a pair of directing elements include a pair of tilting mirrors and a pair of support devices. Sensors may be positioned adjacent to the optical output, one directing element, and to both directing elements. Each sensor detects an amount of light hitting that sensor and generates a signal representative of the amount of light hitting that sensor. A controller receives the signal from each sensor and generates one or more correction signals. A correction signal causes a corresponding directing element to be adjusted in order to minimize losses in optical signal power.
