A scheme for microscopy of relatively large-size objects by using Fresnel zone plate (FZP) coded imaging (FZPCI) is digitally demonstrated. The limit on the source size in zone-plate-based microscopy comes from interference of out-of-focus multidiffraction orders of the FZP with the focused-order image. From the study of the angular spectrum of the coded image, it is shown that noise contribution from higher orders to a lower-order image can be digitally suppressed by selective propagation of spatial frequencies. Similarly, noise from aliasing and noise from lower orders to a higher-order image can be reduced by spatially limiting the coded image. To my knowledge for the first time, the results of digitally performed FZPCI-based microscopy of an object that is three times larger than the first zone of the FZP with a resolution better than 2 µm are presented and discussed.

  6. Be it the application of astronomy, nuclear medicine, or laser-plasma,7,8 the object to be imaged through FZPCI has been a source of one or another kind of incoherent radiation. However, the new applications that arise in the wake of digital FZPCI of this paper, such as optical tomography9 and crystallography, might involve objects that are not direct sources but are illuminated by an incoherent source placed in the vicinity.
