In this experiment, we used from 1 to 5 projectors. In particular, Nayar et al.'s protocol based on a single projector and shifted sinusoids performs descattering but no optical sectioning, whereas our protocol based on multiple projectors and scanning or random binary patterns performs optical sectioning but little or no descattering. 3) but not optical sectioning. The device then collects and recycles energy. The ENERGY STAR
