title: Quantitative characterization of x-ray differential interference contrast microscopy using modulation transfer function.
abstract: Performance of two types of differential interference contrast objectives, i.e., the XOR pattern and the zone-plate doublet, is quantitatively characterized and compared using modulation transfer function. Effects of partial coherence, finite absorption and phase in a complex object, as well as bias retardation are also examined.
