APPLICATION OF MAXIMUM-ENTROPY METHOD (MEM) TO IN-LINE FRESNEL ELECTRON HOLOGRAPHY

We report an application of the maximum entropy method in in-line Fres nel electron holography, in which disturbances due to so-called twin-i mages are a serious problem. The maximum entropy method is known to be robust for noisy data and is especially useful for an application to biological specimens in which electron dose is extremely low. The meth od requires only one hologram, and so is advantageous for reducing rad iation damage. The algorithm of the method and results of numerical si mulation are given.
