Webilluminating the scene with a modulated light source, and observing the reflected light. The phase shift between the illumination and the reflection is measured and translated to distance. Figure 1 illustrates the basic TOF concept. Typically, the illumination is from a solid-state laser or a LED operating in the near-infrared range (~850nm) http://dielslab.unm.edu/sites/default/files/interfacephase-shift_1.pdf
