ABSTRACT:
Apparatus for determining the intensity profile of a high energy laser beam. A target plate having a temperature sensitive paint on the rear surface thereof has its front surface irradiated by the laser beam under analysis. A high speed camera records the isothermal lines formed when the temperature sensitive paint changes from its solid phase to its liquid phase. Isointensity lines are then calculated from the recorded isothermal lines.
