Abstract
Interaction-free measurement using a Fabry-Perot interferometer (FPI) as a measurement apparatus is demonstrated. If the cavity of the interferometer is empty, an incoming photon is transmitted through the interferometer. If an absorbent is placed between the mirrors, the photon is reflected by the first mirror. Information about the presence of the absorbent without losses/interaction is acquired by detecting which way the photon takes.
