NV diamond magnetic field imaging at quantum limited super resolution using adaptive mode sorting
Abstract
This project aims to integrate magnetic field measurements using a Nitrogen Vacancy (NV) center based magnetometer front end—developed by Prof. Saha at IIT Bombay, and spatial super-resolution imaging techniques Prof. Guha at the University of Arizona has developed using adaptive pre-detection mode sorting to attain quantum-limited spatial resolution, to build a system that could improve the spatial resolution of microscale magnetic field sensing, over that achievable by conventional focal plane imaging with a NV based quantum diamond microscope. In collaboration with Prof Saikat Guha s group at University of Arizona, we will integrate the modal-imaging algorithm with a reconfigurable mode sorter (using spatial-light-modulator (SLM)-based multi-plane light conversion (MPLC), into a confocal setup designed for NV Diamond magnetometry to demonstrate super-resolution sensing of a spatial magnetic field. Further, we will explore the possibility of extending the work to widefield magnetic field mapping generated by current-carrying microchips.
