It is recognized that a means of converting electromagnetic fields into visible images would greatly simplify the problem of designing structures to optimize their compatibility with such fields. Two needs must be met to allow such visualization. First, the fields must be transduced into a phenomenon which is capable of being imaged. Second, there must exist a sensor which senses that phenomenon and generates an image visible to the human eye. The bulk of this work was to investigate the parameters and limitations of one possible imaging procedure, called Dye Transfer Modulation (DTM) . On the basis of that work and the development of a new sensor, the AGA Thermovision device was recognized as an exciting alternative to DIM. A brief investigation of its potential was conducted and is presented herein.
