Abstract
An optical receiver is provided that includes an array of photoreceivers. Each photoreceiver may be configured to receive a respective portion of a speckle pattern generated by interaction between an object beam and a scattering medium and each photoreceiver may be configured to generate respective electrical detection signals for provision to processing circuitry for summing of the electrical detection signals. A photoreceiver may include a collector, first detector and second detectors, and first and second optical splitters. The photoreceiver may be configured to generate a first electrical detection signal and a second electrical detection signal based on a received portion of the speckle pattern.
