Figure Lengend Snippet: a Optical transparency of the 1 mm thickness tartrazine solutions with different molar concentrations measured with UV-VIS-NIR spectrometer in the 1.2 to 1.4 µm wavelength range. b Cauchy model-based calculated refractive indices of the tartrazine solutions with different molar concentration in the 1.2 to 1.4 µm wavelength range. c Overall experimental procedure for tartrazine-assisted intact-scalp whole mouse brain vasculature imaging. d Optical configuration of the used OCTA system. BD, balanced detector; C, collimator; CIR, circulator; GVS, galvanometer scanner; L, lens; M, mirror.
Article Snippet: The output of the source was split by a 90:10 fiber coupler (TW1300R2A2, Thorlabs, USA), with the light subsequently routed through a fiber optic circulator (CIR-1310-50-APC, Thorlabs, USA) to the reference and sample arms.
