    A measuring method to detect wall flow topologies by active infrared thermography was developed. Quadcopter rotor blades were studied in typical hover and forward flight conditions, while using a high-power infrared laser to heat the blade surface. By this, the distance between heat source and measuring object could be significantly increased compared to conventional heat :// Flow visualization is a standard non‐intrusive WT technique that provides qualitative information about the flow‐field topology, giving an interesting picture of the whole‐flow behaviour. Two flow visualization techniques, the surface oil‐film technique and infrared (IR) thermography, are applied to a research presented in the chapter Transition mechanism behind a backward-facing step in a supersonic flow Hu, W., Hickel, S. & van Oudheusden, B., 1 Jan , Proceedings of the 11th International Symposium on Turbulence and Shear Flow Phenomena, TSFP 30/07/19 - 2/08/19 Southampton, United Kingdom. 6 p.

    Background: Safety and efficacy are irrebuttable goals in neurosurgery. Methods: We performed a subcortical cavernoma resection in an eloquent area, where we recorded and compared the maximal and minimal brain temperature measured by an infrared thermographic camera and thermometer with the neuronavigation (NN) target location and real anatomical lesion ://
