Abstract
A microlens assembly is automatically aligned (positioned) to facilitate optimal light beam transmission between two spaced-apart subsystems (e.g., two printed circuit boards) supported within a larger system (e.g., a server system). The microlens assembly is controlled by the first subsystem, which also includes a light source (e.g., an emitter array) that generates the light beams by converting data signals. The second subsystem is provided with a receiver capable of receiving the light beams from the light source. The microlens assembly manipulates the microlens according to a raster light beams over a wide area surrounding the second subsystem. The optimal position of the microlens is determined by measuring a strength of each light signal, and by identifying an optimal strength light signal. The microlens assembly is then locked into the position associated with the optimal light signal.
