Apparatus and method of providing separate control and data channels between arrays of light emitters and detectors for optical communication and alignment |
摘要 |
A method of aligning optical data communication channels between system functions comprises: emitting an array of light beams from a corresponding array of data emitters in response to electrical data signals generated from a first system function; emitting light beams from two control emitters in response to electrical control signals generated from the first system function; receiving light beams from the data emitters by a corresponding array of data detectors to form an array of data optical communication channels; conducting electrical data signals reproduced from the received data emitter light beams to a second system function; receiving light beams from the two control emitters by two control detector sections to form two control optical communication channels; conducting electrical control signals reproduced from the received control emitter light beams to a second system function; monitoring a multiplicity of light detectors of each of the two control detector sections to determine an offset in optical channel alignment; and controlling the optical channel alignment based on the determined offset.
