A recently filed patent (Publication Number: US20230296908A1) describes a system that includes two transceivers, each equipped with a beam emitting subsystem, a detector, and an optical assembly. The first transceiver directs a first plurality of coherent beams towards a target and collects radiation reflected from the target through its aperture. The collected radiation includes components corresponding to both the first plurality of coherent beams and a second plurality of coherent beams. The second component of radiation is guided to the first detector, which generates a signal indicating the intensity of radiation corresponding to the second plurality of coherent beams. Similarly, the second transceiver directs the second plurality of coherent beams towards the target and collects reflected radiation, including components corresponding to both the first and second plurality of coherent beams. The first component of the reflected radiation is guided to the second detector, which generates a signal indicating the intensity of radiation corresponding to the first plurality of coherent beams.

A control subsystem associated with both transceivers modifies the parameters of each transceiver based on the signals generated by the detectors. This modification can be achieved by adjusting the beam parameters of the coherent beams or by modifying the parameters of the optical assembly. The system may also include telescope arrangements for directing the coherent beams towards the target and collecting the reflected radiation. Selective optical elements and adaptive optical elements are deployed in the optical paths to transmit, reflect, or direct the radiation as required. The adaptive optical elements have deformable reflective surfaces that can be selectively deformed based on the signals generated by the detectors.

In summary, the patent describes a system with two transceivers that emit coherent beams towards a target and collect reflected radiation. The system uses detectors and a control subsystem to adjust the parameters of the transceivers based on the signals generated by the detectors. The system may also include telescope arrangements, selective optical elements, and adaptive optical elements to facilitate the transmission, reflection, and direction of the radiation.
