Abstract: An overview is given of different state of the art modulator approaches useable as demodulating component in Continuous Time-of-Flight range finding. The first is a spatial optical modulator which can be used in conjunction with a conventional image sensor the second is a single bulk device combining both optical detection and modulation in the substrate. A third performs optical detection and modulation by combining fast conventional photo-detectors with subsequent analog circuitry to achieve modulation and amplification. The different design and implementation challenges are discussed and the properties of the different approaches at both sensor level and 3D-data post processing level are presented.
