Optical magnetic-resonance imaging (MRI) is performed to observe a density distribution of the laser-polarized Cs atoms that diffuse in helium buffer gas at roughly room temperature. Spatial resolution of optical MRI and sensitivity of optical detection are discussed for gaseous atoms in a weak magnetic field. We propose a fast method of three-dimensional optical MRI with parallel processing of signals from a photodetector array, and we discuss its application to the spin-polarized noble gas.
