Hio phase retrieval
Webb29 nov. 2024 · The phase retrieval technique plays a crucial part in image recording and reconstruc- tion. Due to the nature of the high oscillation frequency of light, optoelectronic detector arrays cannot follow and record only the magnitude of the light field, i.e., average light intensity over time. Webbiterative phase retrieval fails not because of the algorithms but because of improper preparation of data for the iterative phase retrieval. The purpose of this work is to …

Webb1 okt. 2006 · The ER and HIO are regarded as identical with respect to the updating at points satisfying the object-domain constraints. As mentioned above, phase retrieval is interpreted as the update with respect to the objective function using the constraints of the object domain and the Fourier domain.
