Provided is an imaging apparatus, including: a light source which irradiates light that is frequency swept an interference unit which diverges the irradiation light into irradiation light, which is to be irradiated on an object to be inspected, and reference light, to generate coherent light from reflected light of the irradiation light from the object to be inspected and the reference light at least two conversion units which subject at least two analog signals, which are obtained by diverging an analog signal of the coherent light, to analog-to-digital conversion an association unit which associates indices of at least two data arrays obtained by the analog-to-digital conversion an integration unit which integrates the at least two data arrays based on the associated indices and an image generating unit which generates an image of the object to be inspected based on a data array obtained by the integration.
