光干渉断層撮影における双方向スキャンに基づくベクトル流速測定

|December 15, 2025

Abstract:

We propose to measure the vector velocity of the flow field based on bidirectional scanning in optical coherence tomography (OCT). Transverse velocity was determined by dynamic light scattering OCT (DLS-OCT) under four introduced transverse synthetic speeds, while axial velocity was obtained by Doppler OCT (DOCT). The flow fields within two straight channels and an improperly welded Y-junction were measured. In vivo measurement on a rabbit was further conducted. Without resorting to system modification and requiring only four scan biases, the proposed method is advantageous in measurement of the vector velocities of a complex flow field.

Uniform Depth Channel Flow

517

Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...
