TERAHERTZ HETERODYNE IMAGING PART I: INTRODUCTION AND TECHNIQUES

The authors present their ongoing work on terahertz heterodyne imaging techniques derived from space science applications and components. In Part I, introductory information and general techniques are provided. Part II contains descriptions of four different heterodyne imaging instruments that have been established at the authors’ facilities. In Part III selected applications are discussed. Parts II and III will appear in subsequent issues of this journal.
