Lunar Laser Ranging Accurately Measures Pulse Laser Pointer
Yunnan Observatory of Chinese Academy of Sciences on the evening of January 22. Major breakthroughs have been made in the research of the lunar laser pointer ranging technology. The research team used the 1.2-meter telescope laser ranging system to successfully detect the laser pulse signal returned by the Apollo 15 lunar reflector several times. Successfully achieved lunar laser ranging for the first time. Lunar laser ranging is performed by accurately measuring the round-trip time of the laser pointer pulse from the ground observation station to the lunar reflector. In order to calculate the earth-moon distance.

This is a comprehensive technology of laser pointer. It covers multiple disciplines such as laser, photoelectric detection, automatic control, space orbit. It is the most accurate technical measure for the current distance measurement. Its observational data are of great value to the study of astronomical geodynamics, terrestrial and moon dynamics, lunar physics, and verification of gravitational theory. The Applied Astronomical Research Group of the Yunnan Observatory of the Chinese Academy of Sciences has long been engaged in the research of lunar laser ranging technology. According to the deputy leader and deputy researcher of the research team, the ranging is improving the pointing accuracy and tracking accuracy. Laser pointers improve detection efficiency and optical transmission efficiency. And achieved after a number of key technical research.
This means that lasers below 100 MW will force everything to burn, and will not completely eliminate it. All lasers above 100 MW are considered burners, but not all laser pointers are the same. The higher the megawatt power, the stronger the burning ability, so if you can only hit a black balloon to light a 100-megawatt match, you cannot cut the tape.
