WebJan 1, 2008 · Ptychography is a nonholographic solution of the phase problem. It is a method of calculating the phase relationships between different parts of a scattered wave disturbance in a situation where only the magnitude (intensity or flux) of the wave can be physically measured. Its usefulness lies in its ability (like holography) to obtain images ...
