摘要: Two properties of a wave, its intensity and colour, are familiar to all us. A third property, phase, is less carries shape information. Quantitative Phase Imaging (QPI), the method discussed in this paper, measures phase It utilises fact that distribution one plane effects after propagation. Many samples at nanoscale objects. For nanostructures, change incident wave strong, while modulation amplitude may be negligible. QPI generates refractive thickness structure these transparent transmission imaging geometry.
