Polarization-sensitive optical coherence tomography (PS-OCT) is a non-destructive and three-dimensional imaging technique that can provide polarization properties, e.g., phase retardation and the optical axis, as well as architectural information similar to conventional OCT from the sample. In this study, we have developed a high-speed PS-OCT imaging engine by using a novel wavelength-swept laser light source based on a high-contrast grating vertical-cavity surface-emitting laser (HCG-VCSEL). Example PS-OCT imaging including the human fingernail junction, 3D plastic printing material, and the chicken breast tissue demonstrated the depth-resolved measurement of the multifunctional information of the sample with PS-OCT and HCG-VCSEL light source at an A-scan rate of 250 kHz.
