LIGHT ON THE INVISIBLE

During the 1950s infrared detectors were built which measured infrared radiation. As these devices did not measure heat rises they had to be kept cold because of contamination due to heat radiation. The stroboscopic infrared TV camera built by Dynarad of Norwood, Mass. displays over 600,000 heat points per second, and its images can be recorded on film or videotape. The Dynarad System is compact and permits viewing the heat transfer as it actually happens. The system can be used to monitor industrial processes, conduct nondestructive tests, and reveal such critical conditions as a crack in a steel furnace, and unlike conventional units, it shows differences in temperature.
