We report on an advanced optical fiber sensing implementation enabling submeter resolution over long distance exploiting Brillouin optical time-domain analysis with differential pulse-width pair. Long sensing distances have been attained thanks to the comb ...
Stereoscopic video content is usually being created by using two or more cameras which are recording the same scene. Traditionally, those cameras have the exact same intrinsic camera parameters. In this project, the exposure times of the cameras differ, al ...
Vision sensors whose pixels asynchronously generate informative output events are gathering increasing interest because they can reduce the data latency, rate, and redundancy, while also increasing dynamic range. This paper proposes such a dynamic vision s ...
Sub-meter distributed optical fiber sensing based on Brillouin optical time-domain analysis with differential pulse-width pairs (DPP-BOTDA) is combined with the use of optical pre-amplification and pulse coding. In order to provide significant measurement ...
The ability of High Dynamic Range imaging (HDRi) to capture details in high-contrast environments, making both dark and bright regions clearly visible, has a strong implication on privacy. However, the extent to which HDRi affects privacy when it is used i ...
The modification of glass nanopipettes with polyethyleneimines (PEIs) has been successfully achieved by a relatively simple method, and the smallest tip opening is around 3 nm. Thus, in a much wider range of glass pipettes with radii from several nanometer ...
Ca2+-evoked transmitter release shows a high dynamic range over spontaneous release. We investigated the role of the Ca2+ sensor protein, Synaptotagmin2 (Syt2), in both spontaneous and Ca2+-evoked release under direct control of presynaptic Ca2+, usin ...
Brillouin scattering is particularly efficient and attractive for the implementation of strain and temperature distributed sensing in optical fibres. Recently a trend has been observed that modern advanced applications require a substantial step towards be ...
Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The optimal reconstruction of these signals is an important topic not only for current astronomical imaging but also that of the next generation of radio t ...
We study the oversampled binary image sensor in [1] under noisy scenario. The binary image sensor is similar to traditional photographic film with pixel value equal to "0" or "1". The potential application of the oversampled binary image sensor is high dyn ...
