  • Optical temperature measurement technique utilizing phosphors
    Patent number: 4075493
    Abstract: A technique wherein an object or environment to be measured is provided with a phosphor material layer that emits at least two optically isolatable wavelength ranges whose intensity ratio depends upon the object or environment temperature. This technique is applied to remote hostile environment point temperature measurements, such as in large enclosed electrical power transformers and other large equipment, to the measurement of surface temperatures, such as in airplane structures being tested in wind tunnels, and elsewhere.
