The ThermAtrace, an innovative infrared scanning instrument was introduced in early 1977 and described in a paper presented at the SPIE 21st International Symposium in August, 1977. Since then the instrument has gained wide acceptance, particularly in energy related applications. This paper reviews the instrument's operating principles, illustrates a wide range of applications experienced over the past year and describes the improvements and refinements made to the instrument as a result of field experience.
