Radiometer Aperture Sheet for Electrical Discharge Temperature

The patent introduces an intermediary relationship between spectral radiometer measurements and blackbody temperature determination. By measuring spectral energy at multiple wavelengths and using Planck's radiation law as a mediator, the system indirectly determines blackbody temperature without requiring direct thermal measurement. The radiometer data serves as an intermediary that, when processed through thermal radiation theory, yields the temperature parameter.

The patent extracts the essential measurement requirement from the complex absorption line method. Instead of analyzing broad absorption lines with multiple assumptions about line shapes and atmospheric constituents, the invention extracts only the necessary spectral energy measurements at specific wavelengths and directly applies Planck's law. This eliminates the need for complex analytical corrections and assumptions while maintaining temperature measurement capability.

The patent performs the measurement action before the harmful thermal analysis process. By measuring spectral energy directly during or immediately after the electrical discharge event, the system captures the radiation data before thermal diffusion and material property changes occur. This preliminary measurement approach eliminates the need for subsequent complex thermal analysis that requires accurate knowledge of material layer thermophysical properties during extreme erosion.
