Abstract

An imaging apparatus includes a light source, a spatial light modulator, a Fourier transform optical system, a photodetector, and a control unit. The control unit sets a first region and a second region on a modulation plane, acquires a light intensity value by setting a light amplitude modulation pattern in the first region and setting a light amplitude modulation in the second region to a non-zero predetermined value, acquires the light intensity value by setting the light amplitude modulation pattern in the first region and setting the light amplitude modulation in the second region to zero, acquires the light intensity value by setting the light amplitude modulation in the first region to zero and setting the light amplitude modulation in the second region to the predetermined value, and acquires a complex amplitude image of a region of an object corresponding to the first region.
