Super-resolution at all scales with active thermal detection

Researchers have found that the temperature increase caused by the probe beam could be utilized to generate a signal per se for detecting objects. Notably, this so-called 'active thermal detection' enables super-resolution imaging at all scales, compared to conventional techniques whose application are confined to microcopy only.
