Abstract

The sensitivity of the photon counting method for the detection of extra-weak optical intensity was improved on the introduction of the enhanced single photoelectron counting technique incorporated with a selected photomultiplier operated under optimum conditions. With this ultra-high sensitive photon counting system it has been possible to measure the difference between the luminescence of the blood of healthy and diseased human subjects (both have extremely weak values).
