Abstract: An optical ranging system includes a demodulation pixel array and a multi-mode light emitter. The multi-mode light emitter includes an illumination source and can generate a diffuse illumination and a discrete illumination in a first and second mode, respectively. Accordingly, in some implementations, the optical ranging system collects distance data via a time-of-flight technique and a structure-light technique. The illumination source can be operable to produce a diffuse illumination in a first mode and a discrete illumination in a second mode.
