We outline some basics of imaging using both fully-coherent and partially-coherent X-ray
beams, with an emphasis on phase-contrast imaging. We open with some of the basic …

Ghost imaging is demonstrated using a polyenergetic reactor source of thermal neutrons.
This enables position resolution to be incorporated into a variety of neutron instruments that …

Advances in x-ray imaging have enabled breakthroughs in medicine, biology, materials
science, and cultural heritage studies. Three-dimensional visualizations of micrometer-scale …

Imaging and edge detection have been widely applied and played an important role in
security checking and medical diagnosis. However, as we know, most edge detection based …

Classical ghost imaging is a new paradigm in imaging where the image of an object is not
measured directly with a pixelated detector. Rather, the object is subject to a set of …

Classical ghost imaging is a computational imaging technique that employs patterned
illumination. It is very similar in concept to the single-pixel camera in that an image may be …

Ghost imaging is a developing imaging technique that employs random masks to image a
sample. Ghost projection utilizes ghost-imaging concepts to perform the complementary …

High-quality ghost imaging (GI) under low sampling is very important for scientific research
and practical application. How to reconstruct high-quality image from low sampling has …

These tutorials introduce some basics of imaging with coherent X-rays, focusing on phase
contrast. We consider the transport-of-intensity equation, as one particular method for X-ray …

The penetrating power of x rays underpins important applications such as medical
radiography. However, this same attribute makes it challenging to achieve flexible on …
