Optical coherence tomography angiography (OCTA) can provide in vivo three‐dimensional microvasculature information of bio‐tissues, but it is sensitive to motion and time‐consuming. To overcome these limitations, we propose an adaptive multiple time interval correlation mapping OCTA with a time‐efficient scanning protocol and motion compensation algorithms. A spectral‐domain OCT with a center wavelength of 850 nm, A‐scan rate of 120 kHz and spatial resolution of 4.1 μm (axial) × 6.9 μm (lateral) is built to reconstruct the microvascular networks in the human arm. By adaptive optimization of the weights of different time interval B‐scan angiograms, our novel OCTA technique achieves better performance with a visible vascular density increase of ~67% and a signal‐to‐noise ratio enhancement of ~11.6%.
