Maximum entropy image deconvolution applied to structure determination for crystal Nd1.85Ce0.15CuO4−δ

Eight [100] images from a through-focus series of tetragonal crystal Nd1.85Ce0.15CuO4−δ were transformed separately into the structure images by means of maximum entropy image deconvolution. The constructed projected structure model based on the deconvoluted image is confirmed by image simulation. It is demonstrated that the image deconvolution is still successful even when some reflections fall in the vicinity of zero cross of contrast transfer function. The effectiveness and advantages of the technique are discussed.
