ToolPythonIntermediate Gerchberg-Saxton algorithm in NumPy: a phase-only hologram for 25 spots phi = np.angle(to_slm(T * np.exp(1j * np.angle(F))))
ToolPythonBeginner MRI k-space reconstruction with numpy.fft: shifts, fold-over, ringing axes[2].imshow(np.where(head, np.angle(image), np.nan), cmap="twilight", vmin=-np.pi, vmax=np.pi,step = np.angle(np.sum((image[:, 1:] * np.conj(image[:, :-1]))[bright]))
