The Laue techniques works by exposing a crystal to a collimated beam of polychromatic x-rays, and collecting the diffracted image onto a 2D x-ray detector. The image is made up of a number of spots in a pattern, that correspond to the orientation and structure of the crystal. Laue diffraction is widely used in the single crystal industry as a quality measure, as well as academic labs worldwide
In x-ray diffraction, the detector is a transducer that counts the number of photons that collide into it. This photon counter gives a digital readout in number of photons per unit time. Below is a figure of a typical x-ray diffraction unit with all of the parts labeled.
