Put in perspective

Researchers from the Paul Scherrer Institute PSI have succeeded in using commercially available camera technology to visualise terahertz light. In doing so, they are enabling a low-cost alternative to the procedure available to date, whilst simultaneously increasing the comparative image resolution by a factor of 25. The special properties of terahertz light make it potentially advantageous for many applications, from safety technology to medical diagnostics. It is also an important tool for research. At PSI, it will be used for the experiments on the X-ray free-electron laser SwissFEL. The terahertz laser developed at PSI is currently the world's most intensive source of terahertz light.
