Simultaneous velocity and temperature field measurement of high-temperature flows // DLR-Mitteilung. 2001. P.377-381. The problem of temperature distribution detection using IR pyrometry in high temperature flows is addressed. Two-wavelength IR pyrometry being a direct and passive technique seems to be attractive method of obtaining 2D or even 3D temperature field as an expansion of conventional PIV or PTV. As opposed to conventional PIV and PTV the inherent blackbody radiation...
