The diverse photoresponses from different energy levels in lanthanide‐doped nanoparticles enables simultaneous generation of multiple point‐spread functions with one doughnut‐shaped excitation beam. In article number 2008847, Fan Wang, Dayong Jin, and co‐workers explore a new imaging modality to extend the capabilities of the engineered point‐spread functions to cover both low‐ and high‐frequency information for optimizing the averaged resolution.
