Two different pulse cleaning techniques for ultra-high contrast laser systems are comparably analysed in this work. The first pulse cleaning technique is based on noncollinear femtosecond optical-parametric amplification (NOPA) and second-harmonic generat
The three-dimensional (3D) mechanical response of the cornea to intraocular pressure (IOP) elevation has not been previously reported. In this study, we use an ultrasound speckle tracking technique to measure the 3D displacements and strains within the ce
An improved multiplier-free feed-forward carrier phase estimation algorithm is proposed for dual-polarization quadrature- phase-shift-keying (DP-QPSK) with coherent detection. The bit error rate (BER) performance, block length effect and linewidth toleran
Real-time in vivo microscopic imaging has become a reality with the advent of confocal and nonlinear endomicroscopy. These devices are best utilized in conjunction with standard white light endoscopy. We evaluated the use of fluorescence endomicroscopy in
