Figure 5: 3D imaging through obscuring material.
From: Single-pixel three-dimensional imaging with time-based depth resolution

(a) Illustration of scene containing a mannequin head with black netting material obscuring the line-of-sight. (b) A photograph of the scene taken from the perspective of the 3D imaging system. The scene depth (c) and reflectivity (d) reconstructed by time-gating the measured intensity data. (e) 3D reconstruction of the mannequin head.
