Abstract
An apparatus and method for determining a temperature in a system having an object, an optical sensor, and a gas flow passing between the object and the optical sensor, sensing, with the optical sensor, a wavelength emitted from the object and indicative of an attenuation, sensing, with the optical sensor, a wavelength emitted from the object and indicative of a temperature of at least one of the object or the gas; and calculating a temperature of the gas using the wavelengths.

A method of determining a temperature in a system having an object, an optical sensor, and a gas flow passing between the object and the optical sensor, the method comprising:
- sensing, with the optical sensor, an attenuation wavelength emitted from the object and indicative of an attenuation associated with the optical sensor;
- sensing, with the optical sensor, at least one temperature wavelength emitted from the object and indicative of a temperature of at least one of the object or the gas;
- and
- calculating a temperature of the gas using the at least one temperature wavelength and the attenuation wavelength.
A method of determining a temperature of a gas, the method comprising:
- flowing a gas between an object and a thermal measurement system, the thermal measurement system comprising at least an optical sensor and a processor;
- filtering, with the optical sensor, light waves emitted from a surface of the object and having various wavelengths;
- sensing, with the optical sensor a gas wavelength associated with a high gas absorption and an attenuation wavelength indicative of an attenuation of the optical sensor;

A thermal measurement system for determining the temperature of a gas disposed around an object, the thermal measurement system comprising:
- an optical sensor spaced from the object a predetermined distance, the optical sensor comprising an attenuation filter associated with an attenuation of the optical sensor determined by an attenuation wavelength reaching the object having passed through the gas;
- an optical detector for translating the attenuation wavelength into a transmitted signal;
- and
- a processor configured to receive the transmitted signal, the processor comprising a storage for storing a set of parameters and a computer for determining at least one parameter from the set of parameters associated with the transmitted signal and calculating a gas temperature of the gas utilizing the transmitted signal and the at least one parameter.
