Abstract: Machine vision systems are widely employed for inspection of blister-packaged pharmaceutical products, and the quality of inspection which can be performed by any vision system is directly related to the quality of images obtained. This paper covers design and selection of illumination, optics, and camera technology to optimize image quality for inspection of blister-packaged tablets and capsules. The nature of image quality is discussed in terms of the optical properties of the materials involved and the machine vision inspection techniques to be applied, and practical application guidelines are presented. !3
