Abstract: A method of enhancing signal-to-noise ratio (SNR) in Brillouin optical time domain reflectometer (BOTDR) is proposed using sparse reconstruction of the Brillouin gain spectrum (BGS) matrix.

Abstract: This paper developed a photonically actuated ultrawideband, two-dimensional transmit array using a Fourier optical lens as a beamformer. Data encoding was developed, in which custom IF ...
