Lensless imaging with extreme ultraviolet light

  • Stefan Witte

Lensless imaging is an elegant approach to microscopy, in which the image formation is achieved using computer algorithms rather than optical components. Such an approach enables high-resolution imaging with radiation for which there are no good-quality imaging optics available, such as extreme ultraviolet (EUV) and X-rays. Furthermore, it opens up the possibility of correcting optical aberrations in an imaging system by computational methods. I will explain the principles of lensless imaging and discuss some recent experimental results, including our efforts to develop an ultra-high-resolution microscope, using table-top coherent EUV sources based on a process called high-harmonic generation.
