摘要： A method includes generating a mixed optical beam using an optical phased array (604) that includes multiple array elements (502), where each array element includes an antenna element (504) and a phase modulator (508). The mixed optical beam includes a combination of (i) an output optical beam (1710) produced by the optical phased array and (ii) a reference optical beam (1728). The method also includes capturing near-field measurements of the mixed optical beam, where the near-field measurements are captured while scanning phase angles of the phase modulators. The method further includes generating calibration data based on the near-field measurements, where the calibration data identifies phase and amplitude responses of the array elements. In addition, the method includes storing the calibration data.
