Single Photon Counting System for Biomedical Applications

Abstract

Single photon counting system for biomedical applications was designed and tested. Examination ofchanges ofan optical signal on a patient's head during stimulation tests (finger taping) was made by the elaborated system.

Ultra Storage-Efficient Time Digitizer for Pseudorandom Single Photon Counter Implemented on a Field-Programmable Gate Array

“…One of the possible solutions to reach this goal is a time-resolved approach. Currently, the most commonly used technique that has been applied to time-resolved DOT is the time-correlated single photon counting technique [4]. Time-correlated single photon counting is based on the detection of individual photons, the measurement of the arriving time of the individual photon, and the reconstruction of the waveform from the time-correlated measurements [5].…”
