A new publication from Opto-Electronic Advances discusses diffraction-limited visible imaging for large aperture telescopes. The deformable mirror used in adaptive optics can change its surface to ...

When measuring with light, the lateral extent of the structures that can be resolved by an optical imaging system is fundamentally diffraction limited. Overcoming this limitation is a topic of great ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...
