Compound pendulum apparatus for determining displacement in laser impulse coupling process

Abstract

The invention provides a compound pendulum apparatus for determining displacement in a laser impulse coupling process. The compound pendulum apparatus comprises a pinpoint pendulum support point, an oscillating arm, a target material storage frame, an adjustable target material clamp, a right-angled arch magnetic storage structure and a compound pendulum oscillating frame and the like. By adopting an axial symmetric structure, all components of the compound pendulum apparatus are detachable and replaceable, and an oscillating point adopts a pinpoint support point way to reduce friction. The compound pendulum apparatus is convenient in disassembling, combining and component replacing and is used for determining infinitesimal displacement during the laser impulse coupling process.

Description

technical field [0001] The invention relates to an impact compound pendulum device, in particular to an electromagnetic compound pendulum device used for detecting the tiny displacement of a target during laser impulse coupling. Background technique [0002] Laser impulse coupling is an important aspect of laser propulsion technology research, and the detection of target displacement caused by impulse coupling is a very effective research and evaluation method. At present, the methods and devices used to detect laser impulse coupling displacement mainly include the horizontal guide rail method and the impact pendulum method. The impact pendulum method is currently a widely used test device due to its simple experimental principle and strong anti-interference ability. and methods. The design of the impact pendulum is mainly divided into two types: single pendulum with suspension wire and compound pendulum with rigid arm. Most of the compound pendulums are integral and non-de...

AI Technical Summary

Problems solved by technology

The design of the impact pendulum is mainly divided into two types: the suspension pendulum and the rigid arm compound pendulum. The compound pendulum is mostly an integral non-detachable structure, and each part of the component cannot be replaced according to actual requirements and usage wear and tear.

In addition, for different displacement measurement methods, such as high-speed photography, optical interferometry, and optical lever method, the versatility of the compound pendulum structure is not high, and it is inconvenient to refit. Compound pendulum device has not been reported yet
