1. Introduction: Carbon Nanomaterial for Photoacoustic Imaging The discovery of carbon nanomaterials (CNMs) has impacted many aspects of nanotechnology and has contributed to significant developments in physics, electronics, optics, mechanics, biology, and medicine [1,2,3].

Abstract Herein we propose a method to mitigate a position mismatch problem for a spectral-domain polarization-sensitive optical coherence tomography (SD-PS-OCT) system that uses a single line-scan detection scheme. A single detector-based PS-OCT detects two orthogonal polarization components as two adjacent A-scan signals in turns. Thus, two adjacent A-scan signals are not scattered at a fixed point in time (position mismatch problem), resulting in uncorrelated signals between them.

The hippocampus is part of the limbic system in the brain, and plays an important role in transmitting signals to other parts of the brain1. It is associated with learning and memory, and regulating emotions2. In addition, it plays a role in regulating the function of the hypothalamus2. Therefore, hippocampal disorders are closely related to brain diseases, such as Alzheimer’s disease, dementia, and epilepsy2. Blood vessels transmit nutrients to the whole body.
