{{Wikitodo|Add relevant papers on state of the art and challenges for improvement}}<br />
<br />
In particular neutral helium matter wave microscopy. <br><br />
'''There is already a scanning variant in use (linked wikipedia page below)''' but this page is about imaging the whole area at once. <br><br />
<br />
== Underwhelming resolution limit far from theoretical limit as of today (2026) ==<br />
<br />
Achievable resolution is still extremely limited compared to the theoretical limit given by the matter waves wavelength. <br><br />
To confirm: barely better than optical microscopy in resolution still, and thus not in real use. <br><br />
<br />
== Showstoppers; Can [[APM]] help? ==<br />
<br />
What stops achivement of theoretical resolution limits?<br />
* Precision of manufacturable Fresnel zone plates. That would be amenable to improvement by [[APM]]. <br><br />
* Other aspects that are harderless obvious to find improvements for (possible yvia [[APM]]. {{Wikitodo|Dig them up again and list them here.}} <br />
<br />
== PROs & CONs ==<br />
<br />
* PRO This technique would have the advantage of extremely high resolution while being extremely gentle to the surface.<br />
* PRO/CON (context dependent) This technique would provide only surface information with no penetration depth as the low enegr yhelium atoms are repuldes by pauli repulsion from the surface.<br />
<br />
== Suspicions to confirm/(refute) ==<br />
<br />
Even with helium atom gas matter wave behaving as a collective <br><br />
and the de Broglie matter wavelength being a lot smaller than the helium atoms <br><br />
The helium matter wave won't penetrate trough gaps well smaller than a helium atom but well bigger than the neutral helium matter wavelength <br><br />
Well, not penetrating beyond an extremely damped evenaescent tunneling wave that practically is not relevant. <br><br />
<br />
No matter how small the matter wavelength (via picked sharp monochromatic kinetic energy) <br><br />
the resolution will always remain limited to a folding of the sphere of the neutral helium atom with the surface atoms. <br><br />
