Quantitative characterization of x-ray differential interference contrast microscopy using modulation transfer function.
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.
متن کاملNanoscale quantitative phase imaging using XOR-based X-ray differential interference contrast microscopy
We propose a quantitative x-ray phase imaging technique using previously demonstrated XOR objectives. The fabrication process of XOR is identical to that of a Fresnel zone-plate and as a result the same finest outermost zone width, thus spatial resolution, can be achieved. A series of phase shifts from 0 to 2p is implemented by shifting the relative position of the grating with respect to the z...
متن کاملDiffractive optical elements for differential interference contrast x-ray microscopy.
In this paper we introduce phase diffractive optical elements (DOEs) that beside simple focusing, can perform new optical functions in the range of x-rays. In particular, the intensity of the wavefront can be distributed with almost complete freedom. We calculated and fabricated high resolution DOEs that can focus a monochromatic x-ray beam into multiple spots displaced in a single or two plane...
متن کاملCompact high-resolution differential interference contrast soft x-ray microscopy
We demonstrate high-resolution x-ray differential interference contrast DIC in a compact soft x-ray microscope. Phase contrast imaging is enabled by the use of a diffractive optical element objective which is matched to the coherence conditions in the microscope setup. The performance of the diffractive optical element objective is evaluated in comparison with a normal zone plate by imaging of ...
متن کاملDifferential interference contrast x-ray microscopy with twin zone plates.
X-ray imaging in differential interference contrast (DIC) with submicrometer optical resolution was performed by using a twin zone plate (TZP) setup generating focal spots closely spaced within the TZP spatial resolution of 160 nm. Optical path differences introduced by the sample are recorded by a CCD camera in a standard full-field imaging and by an aperture photodiode in a standard scanning ...
