On resolution with far field optics

Abstract

lt is common knowledge in optics that, when only far fields are measured, there is a fundamental limit to the resolution given by the wavelength of the light. Yet research continues to beat this fundamental limit. Even a Nobel Prize was awarded for super-resolution some years ago. In this article we consider the apparent contradiction and explain under what circumstances the classical limit of resolution can be beaten. As will
be seen, these circumstances are quite special, but if they can be realised super-resolution is possible.
