Lidar (Laser Detection and Ranging) is an advanced sensing technology that calculates target distance by emitting laser pulses and measuring their return time. It is widely used in fields such as autonomous driving, robotics, and industrial automation. With the development of technology, LiDAR has undergone an evolution from mechanical to semi-solid state and then to solid state. This article will delve into the working principles, characteristics, and applications of solid-state and semi-solid state LiDAR.

For many years, gas sensors have attracted great interest due to their applications in various fields such as medical diagnosis, environmental monitoring, worker safety, and food quality control. For these applications, ideal gas sensors should have high sensitivity and selectivity for tracking targets, fast response/recovery capabilities, low energy consumption, and cost-effectiveness.

In today's rapidly developing technology, our lives are filled with various smart devices, from smartphones to smartwatches, from automotive electronic systems to smart home devices. The reason why these devices can achieve such rich functions is inseparable from a magical technology - MEMS (Micro Electro Mechanical System). MEMS devices, with their unique advantages, are quietly changing our lives.

With the rapid development of autonomous driving technology, the role of in vehicle sensors has become increasingly crucial. They are like the "eyes" and "ears" of autonomous vehicle, helping the vehicle perceive the surrounding environment and make correct driving decisions. Among numerous sensors, LiDAR has become a star technology in the field of autonomous driving due to its high precision, high resolution, and all-weather working ability. This article will delve into vehicle mounted sensing technology and focus on analyzing the core position of LiDAR and its relationship with vehicle mounted sensing technology.

Under the winding blue waves of the Yangtze River, a group of special "fish" are quietly carrying out the important task of protecting the ecology - the intelligent bionic fish developed by Wuhan University, with its highly simulated appearance and advanced technology, has become the main force of ecological data collection in the Yangtze River. Behind its agile posture, the sensor group it is equipped with can be called the "smart eye", allowing the bionic fish to accurately perceive and scientifically analyze, and building a data defense line for the ecological protection of the Yangtze River.

In today's rapidly developing technology, various sensors are like sharp "antennae" that help us perceive and understand the world around us. Force ring sensors, as an important member of the sensor family, play an indispensable role in many fields. So, what exactly is a force ring sensor?
