This is a receiver (20') for use in an optical communications system where the receiver must receive incoming light signals from a plurality of differing fields of view (FOV A - FOV E) and constantly generate an adequate electrical signal therefrom for use by following circuitry (26'). There is a plurality of photodetectors (22) for providing electrical signal (24) outputs as a result of incident light thereon, the plurality of photodetectors being positioned to receive the incoming light signals from respective ones of the differing fields of view. A plurality of switches connect respective ones of the photodetectors into the following circuitry. There is sensing circuitry for sensing a signal quality criteria of respective ones of the photodetectors and decision and switching logic connected to the sensing circuitry and the plurality of switches for connecting and disconnecting respective ones of the photodetectors from the following circuitry to optimize an electrical signal which is a function of incident light output to the following circuitry. |
