Addressed to physical and chemical scientists and engineers, this book provides information on the design, manufacture, and assessment of components with critical dimensions or critical tolerances in the 0.1-100 nanometer range. Such tiny parts are now used in automobile engines, cassette players, and other common products. The 16 lectures presented are from an advanced vacation school on instrumentation and nanotechnology in Warwick, England, September 1990. Among the topics are signal processing, ultrasonic sensors, and nanoactuators for controlled displacements. .
