What is Velocity Distribution Effects in Laser Speckle Imaging about?
This study evaluates the impact of velocity distribution assumptions on laser speckle imaging for calculating speckle flow index (SFI) values, comparing Lorentzian and Gaussian models. The findings indicate that both models yield similar results for low speckle contrast but differ significantly at high contrast, affecting the predicted flow velocities. The derived equations provide a basis for simplified calculations of SFI values, enhancing the understanding of blood flow dynamics in biological tissues.
