Calculation of efficiency of deflected metasurfaces for multi-viewpoint light sources.

	Perspectives	1	2	3	4	Total Efficiency
Left perspective	Beam deflection angle	${-42.30}^{°}$	$-{21.31}^{°}$	${7.40}^{°}$	${33.02}^{°}$	85.74%
	Deflection efficiency	13.97%	27.92%	25.03%	18.82%
Right perspective	Beam deflection angle	${-33.02}^{°}$	${-7.40}^{°}$	${21.31}^{°}$	${42.30}^{°}$	80.46%
	Deflection efficiency	20.83%	23.88%	17.95%	17.80%
