Using the complementary wavelike and particlelike natures of photons, it is possible to make ‘‘interactionfree’’ measurements where the presence of an object can be determined with no photons being absorbed. We investigated several ‘‘interaction-free’’ imaging systems, i.e., systems that allow optical imaging of photosensitive objects with less than the classically expected amount of light being absorbed or scattered by the object. With the most promising system, we obtained high-resolution ~10…

Experimental demonstration of exposure-free imaging and contrast amplification

Interference between waves can yield quite counterintuitive results. Some time ago, Elizur and Vaidman (1993 Found. Phys. 23 987) proposed a way to detect the presence or absence of a perfectly

Interaction-free ghost-imaging of structured objects.

This work integrates entangled photon pairs and interaction-free ghost-imaging to obtain a new imaging technique, IFGI, which can improve image signal-to-noise ratio and is sensitive to phase and polarisation changes of the photons introduced by a structured object.

Classical imaging with undetected light

We obtained the phase and intensity images of an object by detecting classical light which never interacted with it. With a double passage of a pump and a signal laser beams through a nonlinear

'Interaction-free' measurement: possibilities and limitations

The so-called 'interaction-free' measurement is a very interesting quantum effect that allows discovering the presence of an opaque object in a given spatial domain, with the probability that the

We present a tutorial on the phenomenon of induced coherence without induced emission, and specifically its application to imaging and metrology. It is based on a striking effect where two nonlinear

Interaction-Free Polarimetry

The combination of interaction-free measurement and the quantum Zeno effect has been shown to both increase the signal-to-noise ratio of imaging, and decrease the light intensity flux through the
