Gravity wave detection significance. The detection of gravitational waves has lasted for hundreds of years, so it has consumed huge human, material and financial resources. What is the significance of detecting gravitational waves? In fact, on the one hand, as an introduction to Einstein’s general theory of relativity, the existence of gravitational waves is an…

Basic Idea Of Using Laser Pointer Interferometer
One method of gravitational wave detection uses the basic idea of a laser pointer interferometer. Assume that there are four test masses suspended from the ceiling. A monochromatic, frequency-stable laser is emitted from the laser. It is divided into two beams of equal intensity on the beam splitter, and one beam is reflected by the beam splitter…
Laser Launches Green Laser Pointer Online Printer
For a long time, due to the lack of full traceability of drug circulation, drug manufacturers cannot fully understand the downstream sales situation. At the same time, channeling of goods often occurs, which not only endangers the safety of drugs, but also disrupts the market price system, making verification difficult. With the development of the…
Difficulty Of Detecting A Green Laser Pointer With Gravitational Waves
If there are two balls moving around each other like the two black holes in the picture, then it will be incredible. Therefore, if the water surface is space-time, then the water waves are gravitational waves. Gravitational waves cannot be understood as gravitational waves. The essence of laser pointer gravitational waves is equivalent to the ripples of…
The Laser Touches The Ripples Of Time And Space
Today, the major layouts have been refreshed by “gravitational waves”, and wherever the eyes are, they are all related to “gravitational wave discovery”. It turned out that the incident originated from a number of scientific institutions in the United States and Europe who announced on the 16th the discovery of “gravity waves that have never…
Identify The Quality Of The Green Laser Pointer Cutter Purchased
If it is said that the error of the servo motor parameters affects the cutting quality, then the accuracy of the guide rail and the lead screw will directly cause the accuracy of the round hole to fall short of expectations. This is related to the strength of the laser pointer cutting machine manufacturer. Generally, some small…
Laser Processing Efficient And Flexible Laser Pointer
More and more companies are beginning to use laser cutting for circular holes because of the flexibility and efficiency of laser pointer processing methods. The speed of the 500W fiber laser cutting machine at 90 meters per minute is enough to meet the high-speed requirements of many sheet metal processing plants. In addition, the circular hole section…
Portable Medical Device Laser Pointer Will Be Applied
Under the combined action of the gold nanoparticles and the cavity, the directional high-frequency ultrasound drives the dispersion to generate high-speed flow through the acoustic wave driving effect. Wang Zhiming also said that once the microcavity is formed, the gold nanoparticle dispersion can be replaced with pure water or other solutions, and the laser pointer can also…
High-efficiency Pulsed Laser Pointer Drives Liquid Flow
A paper was published in Science Advances, a sub-issue of Science, and scientists realized that under realistic conditions, a pulsed laser pointer was used to drive a continuous high-speed motion in pure water. Driving macroscopic material movement with a laser This is the first time since the invention of a laser to achieve the macroscopic driving force…
Vehicle Biometric Recognition Laser Pointer Technology
A biosensor is an instrument that is sensitive to biological substances and converts its concentration into electrical signals for detection. Because its sensing object is a human characteristic, and the human characteristic has an irreproducible uniqueness, it can be said to be better than many other methods To ensure driving safety, at the same time…
