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.bekindtopets.com/super-super-Handlebar-Stem-for-the-GOTRAX-GXL-V2-Electric-Scooter-hot-choice/
