The fine pattern of light and dark spots is the speckle pattern, an interference pattern of photons backscattered from the block. The Oregon Medical Laser Center and the Dental School at the Oregon Health Sciences University are investigating the use of speckle to characterize the mechanical properties of biological tissues. Applications in dermatology, dentistry, and cardiology are being studied.
