First Claim
1. A method for resolving at least one nitrogen vacancy center, comprising:
- providing at least one diamond structure with one or more nitrogen vacancy centers within a focal location, wherein the focal location is a wide field of view, each nitrogen vacancy center being in either a dark state or a bright state;
applying a magnetic field across the at least one diamond structure;
optically exciting the one or more nitrogen vacancy centers;
switching at least one nitrogen vacancy center from the dark state to the bright state or from the bright state to the dark state by applying at least one microwave pulse to the one or more nitrogen vacancy centers;
detecting a fluorescent response of each nitrogen vacancy center; and
resolving at least one of the nitrogen vacancy centers based on the fluorescent response of each nitrogen vacancy center, the fluorescent response of each nitrogen vacancy center corresponding to its orientation relative to the magnetic field.

Abstract
Techniques for deterministic switch microscopy include resolving at least one nitrogen vacancy center in a diamond structure. A magnetic field can be applied across the diamond structure and the nitrogen vacancy centers can be optically excited. The nitrogen vacancy centers can be switched from a dark state to a bright state or a bright state by a dark state by applying at least one microwave pulse. A fluorescent response of each nitrogen vacancy center can be detected and a nitrogen vacancy center can be resolved based on the fluorescent response of each nitrogen vacancy center as it corresponds to the orientation of the nitrogen vacancy center relative to the applied magnetic field.
