ABSTRACT:
Optical methods and devices for measuring temperature and a second physical parameter, using a single photoluminescent probe material comprised of a single luminophor, and methods and devices for determining temperature-corrected values of said second physical parameter, which can be an oxygen or air pressure or a parameter chosen from the group comprising an electrical current, a magnetic field and an electrical field or voltage. The luminophor is excited sequentially by a first excitation light of chosen first wavelengths and intensity P1which generates a first luminescence light of intensity I1, and a second excitation light of chosen second wavelengths and intensity P2which generates a second luminescence light of intensity I2. The ratio (I2.P1/I1.P2) varies substantially in a known manner with varying temperature, substantially independent of the magnitude of said second physical parameter, thus providing a temperature correction factor to the measurement of said second physical parameter.
