Computational and visible light experiments for x-ray laser holography
Due to the fact that most biological objects of interest are embedded in a complex three-dimensional, it is difficult to estimate the usefulness of x-ray images of complex objects using usual measures of resolution such as Rayleigh criteria. We are approaching this problem for the design and characterization of x-ray holography systems by developing computational tools for the simulation of x-ray hologram formation and for their computational reconstruction. These efforts are closely coupled with a scaled visible light experimental program which validates both the simulations and the reconstruction techniques. The use of simulations allows us not only to establish resolution limits for complex objects but also to vary the parameter space in a controlled manner to optimize imaging system designs. 4 refs., 3 figs.
