Abstract

An optical tomographic imaging apparatus capable of acquiring a two-dimensional or/and three-dimensional tomographic image having higher SNR and quality by cancelling phase change caused by birefringence of a sample in average processing using a predetermined kernel region, and calculating a global phase difference of each pixel in the kernel. The optical tomographic imaging apparatus includes a processing unit configured to: set a predetermined kernel to a B scan image or/and C scan image (volume data) acquired corresponding to a Jones matrix; model the Jones matrix of each pixel in the set predetermined kernel by using one or more unitary matrices to calculate a relative global phase of each pixel; and cancel the calculated relative global phase in each pixel in the predetermined kernel to average each element of the Jones matrix in the predetermined kernel.
