A method includes generating a mixed optical beam using an optical phased array that includes multiple array elements, where each array element includes an antenna element and a phase modulator. The mixed optical beam includes a combination of (i) an output optical beam produced by the optical phased array and (ii) a reference optical beam. 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.
