Panoramic Holography: Toward a Single Shot Stopwatch

August 28, 2008

Panoramic images are captivating in any form, with their wide field of view and extremely high resolution. Now, SSRL scientists have demonstrated a new x-ray holographic technique for imaging wide areas of a nanoscale sample without losing resolution. The results were published in the November 2007 edition of the journal Optics Letters.

Differential Encoding Brings Higher Resolution to X-ray Lensless Holography

September 27, 2010

X-ray microscopy is a useful tool for visualizing functional materials on the nanoscale.  X-ray holography replaces the lens with a computer and obtains an image by Fourier inversion of the interference pattern. While in principle the resolution limit is given by the x-ray wavelength, in practice, the resolution is limited by the size of the reference being used.
