Abstract: A circuit design of a fiber endoscope is described that allows monitoring of hard-to-reach cavities and other partially transparent and/or reflective objects into which it is possible to pass a thin fiber bundle.

Keywords: quantum optics, ghost images, entangled states, biphoton light sources, biophysics, medical physics.
