Ptychography can be realized with various waves including light, electrons, X-rays, terahertz and other waves. Due to absence of optical elements and aberrations, ptychography delivers unprecedented high resolution of reconstructed sample structure. Electron ptychography applied for imaging two-dimensional materials currently holds the world-wide resolution record of 0.4 Å . In this talk, I will present the principles of ptychography and overview its applications.
