| description | An imaging device (1) is provided with a light source (10), a spatial light modulator (21), a Fourier transform optical system (30), a light detector (40), and a control unit (50). The control unit (50) sets a first region and a second region on the modulation surface of the spatial light modulator (21), sequentially sets a plurality of optical phase modulation patterns in the first region, sequentially sets a plurality of identical phase shifts in regions other than the first region when each optical phase modulation pattern in the first region is set, and acquires a light intensity value. A phase image of a region of the object corresponding to the first region is obtained using a phase shift method. As a result, an imaging device and an imaging method capable of acquiring a high-resolution phase image of an object using the spatial light modulator and the photodetector are achieved.
