Abstract: The present application discloses embodiments of a temperature sensor system that uses multiple characteristics of optical radiation signals to determine a temperature of an object. The temperature sensor system includes a light source configured to emit an optical excitation signal propagating to a temperature probe having a phosphor sensing element that emits an optical excitation response signal having a characteristic of phosphorescent radiation proportional to the temperature of the object. The temperature probe emits an optical-excitation-independent signal having a characteristic of black-body radiation emitted by components of the temperature probe. The optical excitation response signal and the optical-excitation-independent signal form a combined signal propagating to a detector that provides a signal representative of the combined signal to a controller configured to separate the signal representative of the combined signal into signals representative of the optical excitation response signal and the optical-excitation-independent signal and calculate the temperature of the object.
