摘要: A mirror image suppression method adapted to an optical coherence tomography (OCT) system is provided. The mirror image suppression method includes the following steps: obtaining a tomography image of an object to be tested by using the OCT system; calculating one real image signal obtained from an nth specific-mode scan for a specific pixel of the tomography image based on image signals obtained from an (n−1)th and the nth specific-mode scans; obtaining one real image signal of each of a plurality of pixels in the tomography image based on the calculation in the step of calculating the one real image signal; and reconstructing the tomography image based on the real image signal of each of the pixels obtained in the step of obtaining the one real image signal to suppress mirror image signals of the tomography image.
