Thermal imaging target

A thermal imaging target configured for shooting and comprising a heat insulation layer, a heat conduction layer, a flow guiding layer, a bottom layer and a self-heating package;

• the heat conduction layer hermetically connected to edges of the bottom layer and comprising an opening formed at the top thereof to form a pocket-shaped structure which is called as a pocket thereof;
• the self-heating package placed in the pocket, and self-heating material arranged in the self-heating package and configured for generating heat;
• the flow guiding layer placed between the heat conduction layer and the bottom layer in the pocket to form crisscross-connected heat dissipation channels therein for guiding the heat generated by the self-heating package to crisscross flow in the pocket;
• the heat insulation layer attached to an outer surface of the heat conduction layer;
• and
• wherein
• heat conductibility of the heat insulation layer is lower than that of the heat conduction layer, so that a temperature difference is formed between the heat conduction layer and the heat insulation layer during a heat conduction process.
