Abstract: A system and method for changing the exterior color of a vehicle is disclosed. The system includes a vehicle with a color change system integrated into the vehicle body of the vehicle. The color change system can change the color of a portion of the vehicle body in response to commands from a color change module running on a computing system within the vehicle. The color change module can detect information about the vehicle's environment to determine an appropriate target exterior vehicle color that contrasts substantially with the vehicle's environment.

Abstract: One some embodiments, a method for tuning optical components includes receiving an optical signal in a waveguide in a photonic-integrated circuit (PIC) and detecting optical outputs of the optical components. The method further includes determining pulse signals for the optical components designed to cause the optical components to each have a peak-resonance wavelength that matches a corresponding wavelength of the optical signal. The method further includes tuning the optical components by sending the pulse signals to the optical components.

Abstract: 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.
