Abstract: 

The tomography executed with mono-wavelength active imaging systems uses the recording of several images to restore the 3D scene. Thus, in order to show the depth in the scene, each recorded image is identified by a different color. Therefore, the 3D restoration depends on the video frame rate of the camera. On the other hand with the multiple- wavelengths range-gated active imaging principle, each emitted light pulse with a different wavelength corresponds to a visualized zone with a different distance in the scene. So each of these visualized zones is identified by a different wavelength. Consequently, it is possible to restore the 3D scene directly in a single color image at the moment of recording, Independently of the video frequency. Furthermore thanks to the range-gating, even if there is a  scattering  embarrassing  environment  in  front  of  the  scene,  the  restoration  can  be performed. The theoretical model and the different experimental results validated this new principle
