An interaction-free measurement system with the polarization-based Mach-Zehnder interferometer structure is described. Properties of the system are investigated especially for nonopaque objects. Here it is shown that the interaction-free measurement of such objects is possible. Our system, whose detection efficiency corresponds to 70% in the sense of interaction-free measurement, was implemented and preliminary experiments were performed to show its feasibility.
