ABSTRACT Laser speckle imaging (LSI) method is a non-destructive imaging technique that can be used to detect optical signals from biological tissues in the form of dark and bright grains called speckle patterns. This study used the LSI system to determine the speckle contrast and refractive index of honey using laser diodes with a wavelength of 650 nm, Riau native forest honey and branded…
