Liquid cell electron microscopy (LCEM) is a useful experimental method of bubble nucleation, which is not understood sufficiently because it is difficult to observe nucleation at nanometer scale in real-time. In our TEM observation, when an electron beam irradiated water, interfacial nanobubbles were generated and grew in a nano liquid cell, whose gap was filled with pure water between two silicon nitride (Si3N4) membranes. In this paper, we introduce Fresnel fringe method, which enable to understand the position of nucleated nanobubbles and the interaction between nanobubbles on the surface of top Si3N4 membrane and the bottom membrane.
