Abstract
A time correlated single photon counting system having a time to digital converter triggered by a laser fire event detector and the reception of a single photon. The system may be used for chemical agent detection based on Rayleigh scattering using optical time domain reflectometry techniques. The system may also be used for Raman detection using frequency to time transformations.
