Non-interferometric methods, including coherent diffraction imaging, phase diversity and transport of intensity equation (TIE), etc., can provide a powerful alternative solution to quantitative phase imaging problems without using complex optical alignment and highly coherent illumination. This chapter outlines the principle of such non-interferometric quantitative phase imaging techniques systematically followed by several numerical simulation in MATLAB®. Furthermore, the high requirement of interferometry on the mechanical stability of instrument strictly limits their applications in lots of circumstances. Thus, it is difficult to apply interferometric methods for imaging with short wavelength including X-ray and high-energy electron beam, where high quality optical elements are not available, and the coherence of radiation beam is much lower than that of common laser. However, these methods rely on the high degree of coherence of light beams to achieve interference, and their accuracy heavily depends on the quality of optical elements adopted and the stability of working environment. Interferometry-based quantitative phase imaging methods support precise phase measurements and are widely used for optical metrology and biological imaging. ![]()
