Gravitational wave experiment device

Abstract

The invention provides a gravitational wave experiment device. The gravitational wave experiment device comprises a laser device and a sound wave source, wherein a light splitting mirror is arranged at a laser emitting end of the laser device; a first reflection mirror is arranged at an outgoing end of a first light beam of the light splitting mirror; a second reflection mirror is arranged at an outgoing end of a second light beam of the light splitting mirror; a first arm is formed between the first reflection mirror and the light splitting mirror; a second arm is formed between the second reflection mirror and the light splitting mirror; a detector capable of obtaining a detection signal is arranged at one side of the light splitting mirror; the detector and the second reflection mirror are arranged at two sides of the light splitting mirror; the sound wave source is arranged in a plane formed between the first reflection mirror and the second reflection mirror of the light splitting mirror; the sound wave source is used for sending sound waves for stimulating gravitational waves to cause length changes of the first arm and the second arm; the detector is used for further detecting light signals caused by the length changes of the first arm and the second arm. According to the experiment device provided by the invention, a gravitational wave transmission manner and a detection principle are demonstrated through the experiment device, and are more visual and clear.

Description

technical field [0001] The invention belongs to the field of experimental teaching and popular science education, in particular to an experimental demonstration device for simulating and detecting the principle of gravitational waves through the experimental device. Background technique [0002] Einstein's general theory of relativity is the foundation of modern physics, and many important achievements have been made in many frontier fields for more than 100 years. Among them, the gravitational wave is the most important prediction of the general theory of relativity, which is of great significance for testing the general theory of relativity itself and revealing its nonlinear effects. For a long time, the research on gravitational waves has mainly remained at the theoretical level, and because the signal is extremely weak, it is very difficult to directly detect it experimentally. With the continuous deepening of theoretical research and the rapid progress of experimental ...

Problems solved by technology

[0004] However, at present, due to the difficulty of theoretical analysis of gravitational wave-related issues and the complexity and cost of detection systems, the research on gravitational waves has been limited to some physicists and a small number of research structures, and has not been used in other researches. broad dissemination and popularization of education among readers and broad student groups
