title: Detection of weak optical images with photon counting techniques.
abstract: A technique has been developed to record very weak images with the use of photon counting techniques. It is shown that the photon counting method is about 2 orders of magnitude more sensitive than a photographic emulsion of comparable signal-to-noise ratio.
