Space-Bandwidth-Speed: the real challenge for optical 3D-sensors

Based on only four physical principles, hundreds of optical 3D-sensors are on the market, each advertised by “high resolution”, “high precision”, etc. Indeed, those features can be achieved by tricky physics and proper information concepts – and nowadays they are taken for granted by customers. The next step, however, is a big challenge: the demand for extremely large space-bandwidth-speed product (SBSP) > 1 billion 3D-data/sec. At the first glance, the SSBP seems to be not that much limited by physics, rather than by (camera-) technology. But waiting for new cameras is obviously not a good solution, as we are shooting at a moving target: customers immediately will demand for more and more SBSP. - So we are forced to ask, if physics and/or new information concepts will provide tools to avoid waiting for better cameras. We will discuss the bottlenecks for the SBSP and will present concepts that deliver a large SSBP, by just exploiting available camera technology. We will furthermore discuss how to solve the "moving target problem" by sensors that allow for an upgrade of the SSBP, if demanded by future applications.
