Much emphasis has been placed in this volume on the objective of bringing about a greater interchange of applicational data from one field to the next -- in other words, a merging of the disciplines
of instrumentation. That is why this handbook includes detailed descriptions of instrumentation applications from nearly all of the major industries and scientific fields. The many areas of instrumentation have been
carefully surveyed and screened in a process of selecting those fields which portray a representative cross section of the subject.
