Book excerpt: Focusing properties of liquid-filled cylindrical acoustic lenses are investigated theoretically and experimentally for d/lambda ratios greater than 15. A mathematical model which includes the effects of the lens shell is described and used to predict directivity patterns. Based on this model, a right-circular cylindrical lens, 40 cm in diameter, was constructed and tested at frequencies ranging from 25 to 900 khz. Agreement of experimental directivity patterns with those predicted demonstrated feasibility of the lens at d/lambda ratios up to 150, a factor of 10 greater than previously reported. Theoretical investigation indicates that for d/lambda ratios greater than 150 the elliptical cylindrical lens shows promise, but fabrication of an experimental model is yet to be undertaken.

Book excerpt: The automation of visual inspection is becoming more and more important in modern industry as a consistent, reliable means of judging the quality of raw materials and manufactured goods . The Machine Vision Handbook equips the reader with the practical details required to engineer integrated mechanical-optical-electronic-software systems. Machine vision is first set in the context of basic information on light, natural vision, colour sensing and optics. The physical apparatus required for mechanized image capture – lenses, cameras, scanners and light sources – are discussed followed by detailed treatment of various image-processing methods including an introduction to the QT image processing system. QT is unique to this book, and provides an example of a practical machine vision system along with extensive libraries of useful commands, functions and images which can be implemented by the reader. The main text of the book is completed by studies of a wide variety of applications of machine vision in inspecting and handling different types of object.
