Nuclear resonance is widely used to characterize nuclear spin polarization and conduction electron spin polarization coupled by a hyperfine interaction. While the macroscopic aspects of such hyperfine-coupled systems have been already demonstrated, the role of local variation in both types of spin polarization has not been elucidated yet. In this study, we applied our nuclear resonance scanning imaging technique to a hyperfine-coupled quantum system and successfully visualized the spatial distribution of dynamic nuclear polarization and electron spin polarization. The results demonstrated the microscopic
