Description

technical field [0001] The technology belongs to the field of spot homogenization, and specifically relates to a high-power laser spot homogenization device. Background technique [0002] A large number of radiation heat flow sensors will be used in the development, testing and flight of thermal protection design of manned spacecraft and returnable satellites, as well as in fire protection, energy, building energy conservation and other industries in the civilian field. In order to ensure the accuracy of these radiant heat flow sensors, it is necessary to establish corresponding heat flow standards and standard devices, the most important of which is a radiation source that can provide stable and uniform thermal radiation energy. [0003] Usually, the standard radiation source method is used to calibrate the radiation heat flow sensor, that is, the black body is used as the radiation heat flow standard. The principle is to trace the radiation heat flow value to the temperatu...
