強度輸送方程式による位相イメージングとそのシングルショット記録

抄録

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.
