Mixing laser beams and X-ray beams

Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing ...

Organic polymeric scintillators excite the X-ray community

X-ray detection is of great importance in diverse applications, such as radiation detection, medical diagnosis, and security inspection. A popular way to achieve X-ray detection is to integrate a photodetector with a luminescent ...

A vertical matrix X-ray detector for multi-energy discrimination

There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...
