Abstract

Different consumer applications using 3D imaging are being introduced in the market. This has been essentially facilitated by the downsizing of semiconductor technologies. Different techniques with more or less advantages are developed with a major lack of efficiency under extreme light conditions. The FMCW 3D imaging technique may be one way to overpass this issue. We present a demonstration of a free space 3D imaging FMCW bench system that is envisioned to be miniaturized for a future integration in portable applications. Our first results show a very good immunity against ambient light. We demonstrate a 3D scene imaging range of 2 meters with only 1𝑚𝑊 optical projected-laser power.
