Abstract
We demonstrate a 3.2MHz-OCT system for inter-volumetric dynamic optical coherence tomography of ex vivo porcine tissue. Employing a home-built Fourier Domain mode locking (FDML) laser with a 1310nm wavelength, the system achieved a lateral resolution of 1.74μm and a frame rate of 612Hz. A motorized XYZ positioning stage enabled the precise acquisition of multiple volumes, which were seamlessly stitched together to generate a comprehensive dataset with a total area of 2.6 × 2.6mm². Validations against histological sections confirmed the system’s ability to visualize cellular tissue structures.
