Phase imaging technique based on the transport of intensity equation (TIE) has been increasingly
investigated in recent years because of some unique advantages such as non-interferometric method,
simple optical system, no need to phase unwrapping, and availability of incoherent light source. We
describe a phase imaging technique using TIE. Also, we describe a single-shot phase imaging technique
using TIE, which can acquire phase information of high-speed moving object. The principle of the
technique and numerical simulation results are presented.
