title: Infrared imaging in liquid through an extrinsic optical microcavity.
abstract: The mutual interference of light scattered inside an extrinsic Fabry-Perot microcavity, fed by a low-coherence light, is exploited to achieve infrared imaging in a liquid environment. The transverse field distribution inside a cavity is shaped by the effect of scattered interfering waves in a lens-free system. Reflectivity and contrast phase maps are extracted through the analysis of the cavity response in the time domain. This approach allows to conjugate noninvasivity, subdiffraction imaging, possible quantitative evaluation of dielectric constants and infrared spectroscopy, making it suitable for biological applications.
