摘要：

An optical time-domain reflectometer operating at room temperature with the single-photon counting technique is described. It features subcentimeter resolution without data deconvolution, and the capability of observing Rayleigh scattering a few centimeters after a reflecting (Fresnel) discontinuity. The key component for the instrument is a silicon single-photon detector of a new design. It is shown that the instrument limitations in the measurements depend mainly on the gain-switched laser diode, which is the laser of choice in portable instruments suitable for field measurements. © 1990 IEEE
