Abstract: A wavelength tuning system determines a temperature calibrated to a DOE of a structured light (SL) projector. The wavelength tuning system includes a camera and controller. The camera captures images of a SL pattern projected by the SL projector. The controller generates tuning instruction.

Using at least some of the captured images, the controller determines the temperature calibrated to the DOE. In one embodiment, the temperature calibrated to the DOE corresponds to a wavelength of light emitted by the light source that result in an estimated minimum power of a zeroth order diffracted beam of the SL pattern.
