- Description
- TECHNOLOGY/BUSINESS OPPORTUNITY Integrated Emissivity and Temperature Measurement of a Surface Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U.S. Department of Energy (DOE), is offering the opportunity to license and commercially develop its Systems and Methods for Integrated Emissivity and Temperature Measurement of a Surface. Background: It is relatively easy to measure the radiation spectrum from a target surface. However, the spectrum itself does not yield information about the temperature without knowledge or information about the emissivity of the surfaces as a function of wavelength and possibly angle. The emissivity is often assumed to be constant or have a prescribed variation with wavelength. In actuality, the emissivity can vary strongly and without regularity as a function of wavelength. A lack of knowledge of the emissivity leads to a large uncertainty in the temperature obtained from the radiation measurement. Description: LLNL?s invention relates to pyrometry and more particularly to systems and methods for implementing pyrometric measurements of simple or complex surfaces of interest. A multi-channel spectrometer together with a light source is used to measure both the emitted and the reflected light from a surface. Systems and methods of this invention add a measurement of reflected and/or incident light to the information used to determine surface emissivity and temperature. Advantages: One feature of this invention is that it uses relative values between channels versus absolute values of the measurement. The use of relative values cancels out geometry factors and eliminates the need for absolute calibrations. Another feature is that it is fast enough to be applied to rapidly moving or changing surfaces. A further feature is that the fiberoptics for the sensors and fiberoptics for the incoming light are located very near the same point in space to automatically correct for the angle of dependence of the emissivity. Potential Applications: This device can be used for radiation thermometry, emissivity and temperature measurement. The device can be used to measure the temperature of a surface that has been shocked or deformed. The measurement can be used to provide information on the pressure?volume relationship for materials under high pressure conditions. Remote and non-contact measurement of temperature is important in many commercial applications involving materials processing or control, such as melting, wafer manufacturing or glass manufacturing. Development Status: This invention is covered under U. S. Patent No. 6,963,816, issued 11/8/05. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information. Please visit the IPAC website at http://www.llnl.gov/IPandC/workwithus/partneringprocess.php for more information on working with LLNL and the industrial partnering and technology transfer process.
