چکیده
We demonstrate a photon-counting optical-time-domain reflectometer (OTDR) operating at a wavelength of 0.85 microm at room temperature with high sensitivity (3 x 10(-15) W) at high resolution (1.5 cm, 150 psec). Measurements of splice losses and Rayleigh scattering losses less then 0.1 dB with centimeter resolution are demonstrated to be possible with such an OTDR.

Multiple windows algorithm for event detection in STFT-BOTDR
Short-time Fourier Transform (STFT) as a class of the time-frequency analysis have been utilised to deliver a fast-speed, accurate and low-variation BOTDR (Brillouin Optical Time Domain Reflectometer) system. The different window functions applied in the signal processing are important to improve the spatial resolution, frequency resolution, and variance of the BOTDR and to detect small event i...
متن کاملHigh resolution optical time domain reflectometer based on 1.55mum up-conversion photon-counting module.
We implement a photon-counting Optical Time Domain Reflectometer (OTDR) at 1.55mum which exhibits a high 2-point resolution and a high accuracy. It is based on a low temporal-jitter photon-counting module at 1.55mum. This detector is composed of a periodically poled Lithium niobate (PPLN) waveguide, which provides a wavelength conversion from near infrared to visible light, and a low jitter sil...

In recent years Global Navigation Satellite System’s signals Reflectometry (GNSS-R) has stood as a potential powerful remote sensing technique to derive scientifically relevant geophysical parameters such as ocean altimetry, sea state or soil moisture. This has brought out the need of designing and implementing appropriate receivers in order to track and process this kind of signals in real-tim...
متن کاملHigh resolution optical time-domain reflectometry based on correlation utilizing an all-fiber chaotic source
We propose a high-resolution optical time domain reflectometry (OTDR) based on an all-fiber supercontinuum source. The source simply consists of a laser with moderate power and a section of fiber which has a zero dispersion wavelength near the laser’s central wavelength. Spectrum and time domain properties of the source are investigated, showing that the source has great capability in nonlinear...
متن کاملApplication of fast reflectometer density profile measurements to investigate plasma instabilities in DIII-D
The high spatial ~>2 mm depending upon plasma conditions! and temporal ~10 ms! resolution possible with the DIII-D solid state profile reflectometer system makes it possible to investigate profile modifications associated with plasma instabilities. In order to take full advantage of this fast sweep and high resolution capability, multiple issues had to be addressed, including fast data acquisit...
