Abstract: In this paper, a technique is developed that can take the depth corresponding to two times depth range of the existing system by including an optical switch in spectral domain optical coherence tomography (SD-OCT) system. The results were obtained by conducting an animal experiment. In order to verify the effectiveness of this technology, optical switch was employed to acquire OCT images sequentially at various depths, to range from the cornea to the retina of guinea pig. Optical switch has a role to match the focus at multiple points of the sample arm for acquiring data of the anterior and the posterior chambers of the eye, and it has the capability of recording the images in real-time.
Keywords: Optical switching mechanism based SD-OCT, anterior chamber, posterior chamber
