主 题:Interferometric particle imaging Bubbles Total internal reflection Tunneling phase shift
摘 要:The interferometric particle imaging technique makes use of the angular oscillations of the scattered light in the forward direction for droplet or bubble *** out-of-focus image consists of fringes,the spacing of which reflects the interference between the surface-reflected light and the twofold-refracted *** internal reflection occurs when the incident light hits the bubble at a large incident *** tunneling phase shift is not included in the geometric optics approximation,which leads to a deviation from Mie *** this work,we modified the formula for describing the fringe spacing by including the tunneling phase shift of total internal *** analysis and experiments showed that the modification is effective for the measurement of bubbles smaller than 60μm.
