Abstract:
Polarization-sensitive optical coherence tomography is a non-invasive imaging technique that is capable of producing two-dimensional or three-dimensional images using the additional properties of light, as well as qualitative examination of the sample. This system, like optical coherence tomography, is mainly used in ophthalmology as a powerful tool for the early detection of eye diseases. PS-OCT can obtain high-resolution cross-sectional images of ocular fibrous structures, such as the retina or anterior segment, which show birefringence when injured. The main purpose of this dissertation is to develop an analytical model of system layout to study important parameters such as birefringence. To achieve this goal, we have identified the main components of the system. Simulation of the model is made using the latest methods of design and simulation of ZEMAX optical systems. Due to the limitations of PS-OCT systems in imaging tissue surface locations, the result obtained from the design of this simulation showed that it will be able to investigate birefringence in the underlying layers (multi-layer with limited depth)
