Polarization phase-shifting point-diffraction interferometer.
A new instrument, the polarization phase-shifting point-diffraction interferometer, has been developed by use of a birefringent pinhole plate. The interferometer uses polarization to separate the test and reference beams, interfering what begin as orthogonal polarization states. The instrument is compact, simple to align, and vibration insensitive and can phase shift without moving parts or sep...
متن کاملEffect of distorted illumination waves on coherent diffraction microscopy
Coherent diffraction microscopy requires a well-defined illumination wave such as a plane wave on a specimen. Experimentally, a small pinhole or a focused beam is often used to reduce the illumination area but they unavoidably distort the waves. The distortion of the illumination wave causes artifacts in the phase retrieval of oversampled diffraction patterns. Using computer simulations, we sea...
متن کاملA Pinhole Camera for Spear 2
A new pinhole camera system has been installed on Spear 2 to measure its vertical emittance. The hard X-rays from a bending magnet source point are imaged on a phosphor screen through a 30 um x 25 um pinhole aperture. The resolution of the system for 8 keV photons is limited to 31.2 um by Fraunhoffer diffraction and is much smaller than the 340 um FWHM vertical beam size corresponding to 0.9% v...
متن کاملTheoretical modeling and evaluation of the axial resolution of the adaptive optics scanning laser ophthalmoscope.
We present axial resolution calculated using a mathematical model of the adaptive optics scanning laser ophthalmoscope (AOSLO). The peak intensity and the width of the axial intensity response are computed with the residual Zernike coefficients after the aberrations are corrected using adaptive optics for eight subjects and compared with the axial resolution of a diffraction-limited eye. The AO...
متن کاملA Super-high Angular Resolution Principle for Coded-mask X-ray Imaging Beyond the Diffraction Limit of Single Pinhole
High angular resolution X-ray imaging is always demanded by astrophysics and solar physics, which can be realized by coded-mask imaging with very long mask-detector distance in principle. Previously the diffraction-interference effect has been thought to degrade coded-mask imaging performance dramatically at low energy end with very long maskdetector distance. In this work the diffraction-inter...
