Integrated diffractive shearing interferometry for adaptive wavefront sensing.
We present theory, design, and preliminary experimental studies for a compact wavefront sensor based on lateral shearing interferometry using a binary phase grating, image sensor, and Fourier-based processing. The integrated system places a diffractive element directly onto an image sensor to generate interference fringes within overlapping diffraction orders. The shearing ratio and the interfe...
متن کاملGroup delay measurement of fiber Bragg grating resonances in transmission: Fourier transform interferometry versus Hilbert transform
Several methods exist to measure the group delay of a fiber Bragg grating. Here, we compare two such methods, namely the Hilbert transform (HT) of the device transmission spectrum and standard Fourier spectral interferometry. Numerical simulations demonstrate that both methods work not only for ideal, lossless devices but also for ones with realistic absorption. Experimental measurements show t...
متن کاملHard X-ray phase-contrast tomography of non-homogeneous specimens: grating interferometry versus propagation-based imaging.
X-ray phase-contrast imaging is an effective approach to drastically increase the contrast and sensitivity of microtomographic techniques. Numerous approaches to depict the real part of the complex-valued refractive index of a specimen are nowadays available. A comparative study using experimental data from grating-based interferometry and propagation-based phase contrast combined with single-d...
متن کاملTransmission phase gratings for EUV interferometry.
The performance of the recently developed EUV phase-shifting point diffraction interferometer (PS/PDI) depends heavily on the characteristics of the grating beamsplitter used in the implementation. Ideally, such a grating should provide throughput of better than 25% and diffraction efficiency, defined as the ratio of the first-diffracted-order power to the zero-order power, variable in the rang...
متن کاملSensitivity of X-ray grating interferometry.
It is known that the sensitivity of X-ray phase-contrast grating interferometry with regard to electron density variations present in the sample is related to the minimum detectable refraction angle. In this article a numerical framework is developed that allows for a realistic and quantitative determination of the sensitivity. The framework is validated by comparisons with experimental results...
