Optical stethoscopy: Image recording with resolution λ/20
TL;DR: In this paper, an extremely narrow aperture along a test object equipped with fine-line structures was used to demonstrate a resolving power of at least λ/20 which is to be compared with the values of λ 2.3 obtainable in conventional optical microscopy.
