Abstract
An observation apparatus includes a light source, a beam splitter, a mirror, a mirror, a cylindrical lens, a lens, a cylindrical lens, a beam splitter, a lens, a frequency shifter, an imaging unit, and an analysis unit. The analysis unit generates a complex amplitude image of each of a plurality of light irradiation directions of object light based on time series data of an interference intensity image output from the imaging unit, and generates a three-dimensional complex differential interference image of an observation object based on the complex amplitude image of each of the plurality of light irradiation directions. The analysis unit obtains a three-dimensional phase image of the observation object based on the three-dimensional complex differential interference image.
