3D OCT imaging of the serpentine mixer. (A) Portion of the serpentine mixer reconstructed from cross-sectional images. (B) Corresponding 3D mixing patterns from the channel extracted from the 3D data set for a flow rate of 5.5 × 10-1 m/sec. Arrows indicate twisting and entrapment of two different fluids. (C and D) Cross-sectional flow profiles for a flow rate of 1.1 × 10-1 m/sec at corresponding positions of the channel (indicated with lines C and D in A) characterized with Doppler OCT. The images are not to scale.
