A first transceiver has a beam emitter that generates first coherent beams, and first optics that direct the first coherent beams towards a target and collect radiation reflected from the target. A second transceiver has a beam emitter that generates second coherent beams, a detector, and second optics having an aperture. The second optics directs the second coherent beams towards the target via the aperture, collects radiation reflected from the target via the aperture, and guides a first radiation component of the collected radiation, that corresponds to the first coherent beams, to the detector. The detector generates, from the first radiation component, a signal indicative of an intensity of radiation impinging on the target corresponding to the first coherent beams. A control subsystem is associated with the transceivers and modifies at least one parameter of the first transceiver based on the intensity signal.

Multiple coherent beam combination systems with reduced number of apertures

A coherent beam combination (CBC) system () includes an array of beam sources (and) generating coherent beams directed towards a target (T). The phase modulators (and) allow adjustment of relative phase offsets of the beams. A detector () monitors an intensity of the radiation impinging on an area of the target (T). A controller () receives the intensity parameter and controls a phase adjustment of the beams according to a deterministic (i.e., quantitative) measurement of a phase offset of each beam relative to a representative phase of the sum of all the other beams. This is achieved by using interferometric techniques, referred to herein as Target In-the-Loop Interferometry (TILI).
