A numerical study of the expansion of a laser-induced plasma is given by using of techniques of computational fluid dynamics. According to the experiment results reported, the density of electrons is assembled on the surface of the ionization area. In the
A novel polarimetric dehazing method is proposed based on three linear polarization images (0°, 45°, and 90°). The polarization orientation angle of the light scattered by the haze particles is introduced in the algorithm. No additional image-processing a
Integrating photoacoustic (PA) and ultrasound (US) into a handheld probe to perform PA/US dual-modal imaging has been widely studied over the past few years. However, optical fluence decreases quickly in deeper tissue due to light scattering and absorptio
