Abstract
The theoretical framework of Part I establishes that the quantum limit to particle tracking sensitivity improves as the measured flux of scattered photons increases and the spatial mode overlap improves. Chapter 5 presented a method to increase the measured photon flux, and thus improve the shot-noise limit. Here we introduce a novel detection method, which unlike conventional quadrant detection, allows engineering of the spatial mode overlap and thus optimization of the shot-noise limit. In principle, this allows construction of a classically optimal tracking scheme.
