3. Focal plane 3D laser imaging techniques

3.1 Introduction to the main instrumental techniques

Numerous non-contact optical techniques exist for determining the geometry of an object in three dimensions. Triangulation telemetry involves acquiring images (without the need for laser sources) and identifying the geometric shape of objects using stereovision and post-processing [S 7 797] .

The simplest 3D LiDAR considers direct measurement of photon time-of-flight. In the case of a single detector, the measurement is carried...
