| Abstract: | The evolution process of the aftereffect of space debris impacting the spacecraft is of great significance to the protection design of the spacecraft. In view of the problems such as overexposure and blurring caused by parasitic fire and smoke when the general high speed camera continuously takes the aftereffect images of space debris impacting the protective panel, a high energy pulsed solid state laser combined with an ultra high speed camera was used to acquire images of space debris after impact. In this method, a multi channel synchronous control module is used to control the ultra high speed camera and the laser light source respectively. When the space debris passes through the test starting device, the laser and the camera work together to complete the shooting work, and obtain multiple images of the space debris flight and impact. Through the ground based simulation of space debris flight impact test, the test method completed the clear recording of several consecutive images before and after impact. The simulated space debris was a steel ball with a diameter of 6mm, the impact speed was 1 000 m/s, the simulated protection plate was two layers of 10 mm steel plate with a distance of 150mm, the vertical distance between the camera and the flight path of space debris is 1 000 mm. and the shooting field was 570 mm×370 mm. It is proved that this test method can be used as an effective test method for image acquisition after space debris impact. |
