Phase unwrapping tutorial. The interferometric phase is ambiguous and only known within 2π. Follow the steps: create an interferogram, perform phase unwrapping, and generate the DEM. Phase unwrapping solves this ambiguity by integrating phase Mar 2, 2026 · Goal In this tutorial, you will learn how to use the phase unwrapping module to unwrap two-dimensional phase maps. After deleting any integer number of altitudes of ambiguity (equivalent to an integer number of 2π phase cycles), the phase variation between two points on the flattened interferogram provides a measurement of the actual altitude variation Jun 13, 2025 · Discover the ultimate guide to phase unwrapping in optical metrology, covering techniques, challenges, and applications for precise measurements. Figures 7. In these cases phase unwrapping is needed to recover the underlying, unwrapped signal. Francis Lilley Pre-requisite: In order to understand this tutorial it is necessary for you to have already studied and completed the “one-dimensional phase unwrapping problem” tutorial before reading this document. Unwrap two-dimensional phase maps Compatibility: > OpenCV 3. Munther Gdeisat and Dr. A key step in SWOT’s phase unwrapping algorithm is to separate the image into regions where a single phase ambiguity is expected to be shared. oaqer rxni clv xdrgfw sew wnofnn xnmga ensm sghr airwfmx
