In this study, we aimed to reduce the measurement time for NMR/ESR using diamond NV centers. Specifically, we applied maximum likelihood estimation (MLE) to electron double resonance (DEER) measurements. We achieved this by solving the Hamiltonian of the NV center to calculate the expected number of fluorescence photons, taking into account the relative position (distance r, angle θ) of the target electron spin. We then constructed a system to estimate the target spin's position by matching measured data with MLE. The practicality of this system will be discussed by comparing it with conventional methods.
