Abstract

Nitrogen vacancy (NV) magnetometers can provide sensitive field measurements via optically detected magnetic resonance (ODMR). Built-in photo-isolation and biocompatibility of diamond have enabled many applications for biological systems. Since small changes in field strength yield commensurate intensity fluctuations, dynamic measurements require fast sensitive detectors such as photomultiplier tubes which inhibits spatial resolution. EMCCD and sCMOS cameras can make sensitive measurements, however, temporal resolution is limited by low frame rates. Recently compressed photography enabled intermediate time steps spatially encoded in a single acquisition. We propose compressed microscopy for capturing dynamic magnetic field fluctuations using sCMOS, moving towards label-free neural sensing.
