6. Mobile laser sheet lighting

Three-dimensional phenomena 3 can be reconstructed by tomographic analysis using sequential recordings of several "planes". For rigorously stationary phenomena, a series of manual displacements of the laser sheet, combined with a set of snapshots, may suffice. The spatial resolution of such an analysis naturally depends on the chosen sampling step, and its temporal resolution on the sheet's displacement speed. In the case of slowly varying flows, a moving mirror...
