Optical Wavelet Signals Processing and Multiplexing [PDF]
EURASIP Journal on Advances in Signal Processing, 2005 We present compact integrable architectures to perform the discrete wavelet transform (DWT) and the wavelet packet (WP) decomposition of an optical digital signal, and we show that the combined use of planar lightwave circuits (PLC) technology and multiresolution analysis (MRA) can add flexibility to current multiple access optical networks.

Acceleration of optical coherence tomography signal processing by multi-graphics processing units [PDF]
Journal of Innovative Optical Health Sciences, 2014 A multi-GPU system designed for high-speed, real-time signal processing of optical coherence tomography (OCT) is described herein. For the OCT data sampled in linear wave numbers, the maximum processing rates reached 2.95 MHz for 1024-OCT and 1.96 MHz ...

SNR enhancement through phase dependent signal reconstruction algorithms for phase separated interferometric signals [PDF]
, 2007 We report several signal reconstruction algorithms for processing phase separated homodyne interferometric signals. Methods that take advantage of the phase of the signal are experimentally shown to achieve a signal-to-noise ratio (SNR) improvement of up
