Quadrature amplitude modulation is implemented in a single pixel imaging system, enabled by all‐electronic metamaterial spatial light modulation. Experimental images at 3.2 THz are acquired to demonstrate the expected doubling of efficiency over previous single pixel systems. Results are deterministic and show no loss of image fidelity compared to nonquadrature methods.
