PROBLEM TO BE SOLVED: To obtain an accurate tomographic image by removing information (for example, an autocorrelation component) based on the intensity of reference light from synthetic light.SOLUTION: An imaging apparatus which captures an image of an inspection object by using optical coherence tomography includes: switching means for switching a state to one of a synthetic light detection state and a reference light detection state control means which controls the switching means so that the switching means switches from the reference light detection state to the synthetic light detection state if a light quantity of measurement light is equal to or smaller than a threshold in the reference light detection state and acquisition means which, after detection of the synthetic light, acquires a tomographic image where information based on the intensity of reference light has been reduced, from information of the tomographic image of the inspection object based on the intensity of synthetic light.COPYRIGHT: (C)2013,JPO&INPIT【課題】 合成光から参照光の強度に基づく情報(例えば、自己相関成分)を除去し、精度の高い断層画像を得ること。【解決手段】 光干渉断層法を用いて被検査物を撮像する撮像装置が、合成光を検出する状態と参照光を検出する状態とのいずれか一方に切り替える切替手段と、参照光を検出する状態において測定光の光量が閾値以下である場合に、参照光を検出する状態から合成光を検出する状態に切り替えるように、該切替手段を制御する制御手段と、該合成光を検出した後に、合成光の強度に基づく被検査物の断層画像の情報から、参照光の強度に基づく情報が低減された断層画像を取得する取得手段と、を有する。【選択図】 図1
