The present disclosure describes intelligent illumination systems that use modulated light. For example, in one aspect, a method includes producing, by a light source, modulated illumination in a visible part of the spectrum, detecting three-dimensional image data based on at least a portion of the modulated light produced by the light source and reflected by a scene, and changing a characteristic of the modulated illumination based on the detected three-dimensional image data.
