Coherent Diffraction Imaging

Coherent Diffraction Imaging or CDI, is a specific-purpose display reconstruction system for tiny objects in the nanoscale. It supports both 2D and 3D imaging, and as such is an excellent imaging method for enlarging nanoscale structures for examination and manipulation.

It can use many different wavelengths, from Xrays right through to photon streams. What matters is not the wavelength, but that a coherent stream of wavelike particles impacts upon the object to be imaged. This beam is diffracted by the object to be measured, and the diffraction pattern sampled by a detector. This pattern is then used to reconstruct the original object as a 2D or 3D model for use elsewhere.

Ultrasensitive Imaging: Hunting Every Photon
As the demands for precise imaging in fields such as medicine, astronomy, and real-time machine vision in hostile environments continue to increase, so the demands placed on imaging equipment become ever more stringent. An imaging method based on Single Photon Avalanche Photodiodes (SPAD) offers the potential to ease this bottleneck greatly.
