Fig. 7. Visualization of the optical diffusion under a semi-transparent white glass globe. (a) Schematic of experimental setup used to capture the speckle patterns from the optical diffusers. (b) A photograph of experimental setup. Scale bar = 12 cm. (c) 450, 533 and 633 nm beams illuminating the glass globe without a diffuser. Scale bar = 12 cm. (d) Laser beams were passed through the diffusers producing different speckle patterns and intensities. Scale bar = 6 cm.
