A shoe-fitting fluoroscope was a metal construction covered in finished wood, approximately 4 feet (1.2 m) high in the shape of short column, with a ledge with an opening through which the standing customer (adult or child) would put their feet and look through a viewing porthole at the top of the fluoroscope down at the X-ray view of the feet ...
Advanced X-ray Imaging Satellite (AXIS) is a space telescope under development by NASA for launch in 2032. [1] It is a NASA Probe mission concept designed for high angular resolution X-Ray imaging. [2] The mission goals are to examine galaxies over cosmic time, feedback in galaxies, Black Hole strong gravity, Dual AGN, the high redshift universe.
Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
These X-ray tubes may have been used by Professor T.H Laby's X-ray group, which was a priority research topic there. This interest was sparked by the appointment in 1889 of Professor T. R. Lyle. Lyle, who was head of the school until 1915, is thought to have been the first person in Australia to have taken an X-ray photograph iii.
The Athena X-ray observatory consists of a single X-ray telescope [8] [9] with a 12 m focal length, with an effective area of approx. 1.4 m 2 (at 1 keV) and a spatial resolution of 5 arcseconds on-axis, degrading gracefully to less than 10 arcseconds at 30 arcminutes off-axis. The mirror is based on ESA's Silicon Pore Optics (SPO) technology.

The analysis of the energy dependence of the emitted photons is the aim of the X-ray emission spectroscopy. [1] [2] [3] XES is also sometimes referred to as X-ray Fluorescence (XRF) spectroscopy, and while the terms can be used interchangeably, XES more often describes high energy resolution techniques [4] while XRF studies a wider energy range ...
Chandra uses four pairs of nested mirrors, together with their support structure, called the High Resolution Mirror Assembly (HRMA); the mirror substrate is 2 cm-thick glass, with the reflecting surface a 33 nm iridium coating, and the diameters are 65 cm, 87 cm, 99 cm and 123 cm. [47] The thick substrate and particularly careful polishing ...
