A BRIEF HISTORY OF DIGITAL THERMAL IMAGING:
https://o2-wellness.com/medical-thermal-imaging/
“n 1860, American astronomer Samuel Pierpont Langley invented the bolometer which is a device that measures infrared or thermal radiation.
And in 1929, Kálmán Tihanyi, Hungarian physicist invents infrared-sensitive electronic television camera which was capable of capturing thermal images.”
STAGES IN THE DEVELOPMENT OF DIGITAL THERMAL IMAGING:
“Remote sensing of infrared radiation first developed in the 1940s and has continued to develop steadily since 1960. Modern high speed and high resolution camera systems have now reached a dramatic level of performance at more modest costs, which medicine can now employ for non-invasive and quantifiable imaging. “
PIONEERS IN THE DEVELOPMENT OF DIGITAL THERMAL IMAGING:
The discovery of infrared radiation by William Herschel in 1800 led to John Herschel’s study of solar radiation that he imaged by evaporography. This he termed a thermogram.
“The measurement of temperature particularly with reference to medicine, had a slow beginning with the primitive thermometers of the sixteenth century. Dr Carl Wunderlich, a great pioneer in clinical thermometry showed the real significance of the use of temperature measurements for both diagnoses of fever and also for monitoring the course of temperature in relation to the medical condition of his patients”
