Quantitative 3D phase retrieval techniques are based on either interferometric techniques such as holography or noninterferometric intensity-based techniques such as the transport of intensity equation (TIE). Interferometric techniques are vibration-sensitive and often use a reference beam requiring complicated optical alignment. In this work we develop a simple. fast. https://www.chiggate.com/philadelphia-eagles-mitchell-ness-head-coach-hoodie-sale/
