Abstract: A depth measurement assembly (DMA) measures depth information of an object in a local area. The DMA includes structured light projector, a depth camera assembly, and a controller. The structured light projector projects structured light patterns into the local area. The structured light projector includes a diffractive optical unit that includes diffractive optical elements (DOEs) and selects a DOE.

In some embodiment, the diffractive optical units selects multiple DOEs associated with multiple structured light patterns. The structured light pattern is projected into the local area by a projection assembly of the structured light projector and illuminates the object. The depth camera assembly captures images of the object. The controller uses the captured images to determine depth information of the object.

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. The tuning instructions cause a wavelength regulator of the SL projector to set a light source of the SL projector to different temperatures. The tuning instruction also cause the camera to capture images of the structured light pattern at each of the different temperatures. 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.
