Abstract
A combination of quantitative background oriented schlieren (BOS) and particle image velocimetry (PIV) is used to simultaneously measure 2D temperature and velocity distribution inside a thin fluid layer, where optical access is limited to one side. Application of optical filters allowed us to perform simultaneous BOS and PIV measurements. Instantaneous temperature gradient fields are acquired by implementing a highly reflective surface below the fluid layer. Temperatures are estimated with accuracy of the order of 10 mK by 2D integration of the temperature gradients.
