We previously proposed a bimodal incoherent digital holography system to implement both three-dimensional and infinite depth-of-field (DOF) imaging. In this paper, we reveal the basic operation of our system in detail to control its imaging properties such as transverse magnification and DOF. We numerically evaluated the effect of rotational shear on these imaging properties, and the results indicate that it is possible to control both properties by simply changing the rotation angle of a light instead of replacing an imaging lens.
