Photon counting image acquisition technique and its applications

An experimental set-up of photon counting real-time image acquisititon system is introduced, wherein a photon image head (an image intensifier with high radiant emittance gain) is coupled with a high frame rate CCD camera by a super powerful relay lens. The restricitons on luminous emittance of object are analysed for multiphoton and single photon imaging modes. The methods of determining readout noise-the major comprehensive specification of system is introduced. The application examples of system in adaptive optics wavefront sensor operated with a faint object, and in experimental study on the optical wave-particle duality and the uncertainty relation are presented.
