Abstract
The optical surface quality of pharmaceutical tablets was inspected us ing a computer-generated hologram based sensor. The image information was related to the optical surface quality of pharmaceutical compacts compressed using different tableting powders as matrix materials for d rugs. The role of the compression and thermomechanical properties caus ed by sensing laser beam on the surface quality are discussed.
