 # Example 06: NSC Phase

 Last update: 09.03.2026 

Ex 6: A file with a simple spherical wavefront is created using a point source, which propagates to a detector. Rather than using a Detector Viewer to extract the phase of the wavefront, the GetAllCoherentDataSafe() method is used to extract a 2D array to manually calculate the phase. The GetAllCoherentDataSafe() method will only return the real & imaginary parts of the electric field, so atan2(image, real) is used to calculate the phase. Note that for C++, GetAllCoherentData() method is used to return a 1D array which is then read out in nested FOR loops and provides the 2D phase data in the correct orientation.
