Paper Abstract

Multichannel photon-counting fluorimetric systems using optical fiber dynamic memory with high time resolution and high data-gathering efficiency are presented. The principle of operation is based on the vernier chronotron technique. A measurement system using two single-mode optical fiber loops in conjunction with pulsed laser diodes and avalanche photodiodes was described in detail. The feasibility of rapid measurement was indicated. The extremely low loss, good linearity, and large available time-bandwidth of single-mode fiber allow signals to propagate large distances without significant attenuation or distortion, so that good stability as well as high time resolution of the measurement system can be constructed. In order to simplify the system and improve system performances, other modified systems using optical fiber dynamic memory are discussed.
