The Temporally Resolved Thermal Sensor is a multi-color optical pyrometer for non-invasive measurements of high-speed, high-temperature events.  The battery operated unit (fully-functional breadboard shown here) is simply aimed at the object or interest with the assistance of a visible aiming laser.  A Graphical User Interface (GUI) steps the user through automated calibration, alignment, and sensor operation.  Data is both presented graphically to the user (computer not shown) and is stored for additional off-line processing and data retrieval.  The Temporally Resolved Thermal Sensor was originally developed by A2Z Technologies Corporation for the US Navy under the Small Business Innovative Research (SBIR) Program.     

Breadboard

Applications of the sensor includes the measurement of high-speed, single-shot, high-temperature events.  One such example is during the testing of certain reactive materials currently in development.  The plot below shows data collected by the functional breadboard during a live-fire reactive material test.
