Open doors for imaging with cognizance Keith A. Nugent ARC Center of Excellence for Coherent X-beam Science & School of Physics The University of Melbourne Australia

Outline of Talk What would we be able to go for in 2013? Prologue to CDI – brief Fresnel CDI (FCDI) Quantitative stage estimation Application to jungle fever tainted red platelet Keyhole FCDI – imaging stretched out articles Application to innovation issue Early 3D comes about Conclusions

Approaches to Coherent Imaging To Image broadened protests in three-measurements with 5nm determination Holography Recent work at BESSY Limited way to high determination Phase-differentiate Very widely utilized Low determination Ptychography SLS – Oliver Bunk Extended items, high determination? CDI Plane wave episode Isolated articles Curved occurrence wave

Coherent imaging techniques are being produced. Lucid Field Impose Measure Intensity, Keep Phase z Impose "bolster" Guess Phase

Unique! Use earlier learning of the episode wave to recoup the "leave surface wave" leaving the protest

Quantitative Phase Measurement Average AFM tallness and reproduced thickness for the four regions demonstrated in Fig 2(c). Region AFM (nm) FCDI (nm) 1 370 ± 8* 360 ± 29 2 344 ± 7 377 ± 28 3 308 ± 15 297 ± 32 4 348 ± 12 321 ± 19 *Errors are evaluated from the difference in the statures recuperated inside every locale, as this incorporates characteristic tallness variety the mistakes are in this manner preservationist. Use earlier information of the episode wave to recuperate the "leave surface wave" leaving the protest Clark, J.N., et al., Quantitative stage estimation in intelligible diffraction imaging.

What do we mean by "support"? Support is translated marginally diversely here –the structure to be reproduced is the reasonable leave wave, including the enlightenment, not the diffusing article itself.

X-Ray CDI

Have accomplished a determination of ~15nm! B Abbey et al, " Keyhole Coherent Diffractive Imaging", Nature Physics , Published on the web March 9, 2008

Exceeds determination of STXM with same optics, by an element of ~4!

All of the calculated and methodological pieces are set up for us to accomplish 3D imaging of expanded articles with 5nm spatial determination
