Event Details & Abstract: 

Coherent diffraction imaging (CDI), also known as “lensless imaging”, has advanced very rapidly over the last decade, and is now revolutionizing X-ray imaging. From its first demonstration using X-rays in 1999, to recent advances in three-dimensional imaging of dislocations in nanoparticles with atomic resolution, CDI has effectively filled the gap between atomic-scale and visible imaging, with the possibility for unprecedented temporal resolution. Nearly coincident with the development of CDI, high-harmonic generation from ultrashort pulses is now producing coherent laser-like beams spanning the entire electromagnetic spectrum from the UV to the soft X-ray region. This talk will review recent advances in tabletop-scale CDI using coherent high harmonic beams, which have achieved record imaging in both transmission and reflection modes. I will also provide some perspective on the future of tabletop CDI.
