A 240x180 130dB 3µs Latency Global Shutter Spatiotemporal Vision Sensor

Event-based dynamic vision sensors (DVSs) asynchronously report log intensity changes. Their high dynamic range, sub-ms latency and sparse output make them useful in applications such as robotics and real-time tracking. However they discard absolute intens ...

Infrared imaging of temperature profiles in microreactors for fast and exothermic reactions

Albert Renken, John Richard Thome, Lioubov Kiwi, Navid Borhani, Madhvanand Namadeo Kashid, Julien Haber

Though microreactors provide high heat transfer rates, temperature profiles are formed in case of fast and highly exothermic reactions. A method based on non-intrusive infrared thermometry has been developed to track these profiles quantitatively with a re ...

Measuring the thermal balance of a snow avalanche

Michael Lehning, Betty Sovilla, Tobias Jonas, Walter Steinkogler

Avalanches can exhibit many different flow regimes from powder clouds to slush flows. Flow regimes are largely controlled by the properties of the snow released and entrained along the path. Recent investigations showed the temperature of the moving snow t ...

Influence of Thermocouple Thermal Inertia in Impingement Heat Transfer Experiments Using Transient Techniques

Peter Ott, Alexandros Terzis, Bernhard Weigand, Guillaume Wagner

A typical transient heat transfer experiment for an impingement cooling configuration requires usually a temperature step in the flow. A moving isotherm of the liquid crystal surface coating is then monitored using a video camera. However, for small imping ...
