Mikheev A.V., Zubtsov V.M. Simultaneous determination of temperature and velocity flow fields by enhanced two-color PTV technique // ICIASF Record, International Congress on Instrumentation in Aerospace Simulation Facilities. 2003. P.320-327. Inherent or laser induced irradiation of individual solid/liquid tracer particles or distinguishable groups of molecules (e.g. injected into hot flow in the form of liquid evaporating droplets) is examined as an information source of both temperature and velocity...

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...
