Notes:
The world's first time-of-flight (TOF) 3D range camera without moving parts, based on a custom solid-state imaging device is described in this article. With the single exception of the smart-pixel array, only electronic and optical standard components are used. The range camera does not need any mechanically scanning parts. It acquires 10 range images per second and achieves a resolution of a few centimeters over a distance range of 10-20 meters for non-cooperative targets. The illumination source consists of 160 LEDs, modulated at 20MHz, with a total optical power of about 800mW. The description of the smart pixel's working principle and the presentation of our first 3D measurements are completed with a discussion of the theoretical limitations and a comparison with the system performance.
