Embodiment approach 1

[0038]

[0039] The purpose of this embodiment is to provide an infrared point source deflection device, which is used to protect the target in the final guidance stage. For this reason, the device needs to be able to reach a certain temperature range and achieve a high frame rate when energized and heated. This enables the device to simulate the infrared radiation characteristics of the target to be protected when powered on. In actual use, multiple infrared point source devices can be used in combination, such as using multiple point sources to form a surface source, to achieve the effect of being close to the actual target.

[0040] This embodiment provides an infrared point source deflection device, including: a metal sheet 11 in contact with the electrode 10, which can realize heating and temperature rise when energized, and can realize natural temperature reduction, and is used for achieving the maximum temperature that can be achieved through the heating and natural t...

Embodiment approach 2

[0053]

[0054] The method in this embodiment is implemented based on the device in Embodiment 1, and the method includes:

[0055] Step S1: Determine the energizing voltage according to the infrared radiation characteristics of the target. The energized voltage includes voltage value and energized frequency.

[0056] Step S2: Carry out electric heating on the metal sheet according to the electric voltage.
