Laser fusion backscattered light beam analog device

Abstract

The invention provides a laser fusion backscattered light beam analog device to solve the problems that the analog devices in prior art have low calibration accuracy and require much time and effort. The analog device comprises a loading plate, two collimating holes and corresponding monitoring cameras and a universal light beam analog lens. The universal light beam analog lens comprises two orthogonal rotating joints of rotating shaft, and an analog target spot is arranged on the junction of the axis of the rotating shaft. A first pentaprism is arranged on the light path of an input light of the universal light beam analog lens, a first rectangular prism is arranged on the emitting light path of the first pentaprism, a second pentaprism is arranged on the emitting light path of the first rectangular prism, a second rectangular prism is arranged on the emitting light path of the second pentaprism, a third rectangular prism is arranged on the emitting light path of the second rectangular prism, a fourth rectangular prism is arranged on the emitting light path of the third rectangular prism, and light beam analog lenses are arranged on the emitting light path of the fourth rectangular prism. The analog device provided by the invention has advantages of high calibration accuracy, high efficient and ease of assemble and adjust.

Description

technical field [0001] The invention relates to a beam simulation device, in particular to a simulation device for simulating a backscattered beam emitted from a target in a laser fusion target chamber. Background technique [0002] Laser nuclear fusion is a commonly used artificial controllable nuclear fusion. It has very important research significance in both civil and military: to provide mankind with an inexhaustible clean nuclear energy; to develop "clean" (No radioactive pollution) nuclear weapons, the development of high-energy laser weapons; partial replacement of nuclear experiments. [0003] Therefore, laser nuclear fusion has been highly valued by the world's nuclear powers. Since the second half of the 1970s, Russia, the United States, Japan, France, China, and the United Kingdom have successively started the development of high-power laser drivers. The United States is in a leading position in research in this field, and in 2009, the super-large laser drive de...

Problems solved by technology

The disadvantage is: there is a defect of covering the surface with points, and the calibration uncertainty is large; in addition, each system needs to build a calibration light source separately, which is time-consuming and labor-intensive

[0010] However, the diameter of the target chamber of the Shenguang-Ⅲ main engine is as high as 6m. Although there is an equipment delivery platform, personnel need to enter the vacuum target chamber for high-altitude debugging operations, which is dangerous and time-consuming; moreover, the uncertain factors of this kind of sampling calibration are relatively large.

This method is extremely inefficient if the optical path to be measured is large in size
