We obtained different degrees of multiplexing from three multiplexing schemes: (a) Scheme (1)—fixed magnification and detection efficiency with different scaling of the same pinhole pattern and their corresponding sampled projection images (b). (c) Scheme (2)—fixed detection efficiency and changed magnification by changing the collimator length and their corresponding sampled projection images (d). (e) Scheme (3)—fixed magnification and changed detection efficiency by adding more pinholes and its corresponding sampled projection images (f).
