Laser displacement sensor‍ is used in the aerospace field. It can be used in conjunction with space technology to achieve diversified applications. Many people only know that it has a high proportion of profits at sea, but in fact, it is also necessary to use it in aerospace. It is one of the participants in the space collision early warning system, which is one of the participants in the space collision warning system. What are the applications of the wide-spot laser displacement sensor in the satellite field?

What are the applications of laser displacement sensor in the satellite field

1. Accurately determine the Earth's gravitational field model and its time-varying

The blind area of the laser displacement sensor is small. In the process of studying the position change of the earth's center of mass, the laser displacement sensor technology measures the current accurate gravitational constant GM. It uses laser satellites with different orbital inclinations and altitudes to accurately measure the earth's gravitational field model. , and measured the seasonal variation of the low-order spherical harmonic coefficient of the earth's gravitational field; at the same time, the laser displacement sensor also obtained the periodic changes of the position of the earth's center of mass, including seasonal and interannual changes, and the changes of the earth's gravitational field reflected the earth's gravitational field. Laser displacement sensors have important research value in the complex motion and interaction process of interior and various layers (including ocean, atmosphere, groundwater, ice, etc.).

2. Monitoring global crustal plate movement

The long-term observation data of the laser displacement sensor can accurately determine the geocentric coordinates of the ground station, and the calculation of the coordinates of the high-precision station makes it possible for people to monitor the plate movement. Using data obtained from laser displacement sensors, station velocities and rates of change of baselines between stations have been estimated for dozens of stations. If the station is located in the rigid part of the plate, its station velocity represents the plate motion, and the relative motion between the plates can be calculated by using the rate of change of the station baseline and the station velocity.

The laser distance sensor can fragment the information and then integrate it to realize the distance measurement. The error obtained by this kind of sensor is relatively small. In the future development of aerospace, orbital early warning will be the main breakthrough. Therefore, even if the laser distance Sensors cannot independently carry out scientific exploration of satellites, but they still have great application value in the process of satellite orbit identification.

Introduction to Laser Displacement Sensor ‍Repairing Composite Fiber Materials

The laser displacement sensor can be modularized to make the assembly and adjustment more convenient. Due to the high access threshold of its various components, its production time is greatly prolonged. This kind of equipment has strong feasibility. The laser displacement sensor is also It can be used in the chemical industry, such as repairing composite fiber materials, then the following is an introduction to the repair of composite fiber materials with laser displacement sensors.
