Abstract : This is the final report on AFOSR #F49620-93-1-0603 entitled: "Fiber Optic Infrared Spectroscopy for "Smart" Processing". The report is divided into six sections. An Introductory paragraph contains a brief description of the background and the objectives. In-situ real time monitoring of chemical and physical changes during processing of reactive materials, polymer-forming and non polymer-forming alike, is of crucial importance to scientists and engineers engaged in efforts to optimize processes and products in various industries, from chemical and pharmaceutical to electronic and aerospace. Information collected in-situ by sensors is transmitted in real time to the process computer whose task is to control the system parameters by taking corrective actions without the need to examine the output streams and thus to guide the process along an optimum path. The principal elements of an in-situ process control loop are the signal source, the transmission line, the sensor and the detector. jg
