In the current era of rapid technological development, the demand for smart devices to perceive their surrounding environment is increasing day by day. Sensors and LiDAR, as the two key technologies in the field of intelligent perception, are like two brilliant twin stars, illuminating the path forward in the era of intelligence. The close connection between the two has also become an important force driving technological progress.

Have you ever noticed the "invisible guardians" around you as you shuttle through the streets and alleys of the city every day? From finding a parking spot to breathing in the air, from traveling at night to ensuring water safety, sensors are like the "nerve endings" of the city, reshaping our living experience with the power of technology!

In today's rapidly developing technology, sensor technology has become a key support in many fields. Among them, quartz flexible acceleration sensors play an indispensable role in multiple industries due to their unique performance advantages. Its three main uses are reflected in the aerospace, automotive industry, and oil exploration fields.

Recently, with the acceleration of industrial intelligence, stress wave sensors, as a key technology for equipment condition monitoring, are receiving increasing attention. This type of sensor can capture stress wave signals in real-time during device operation, providing accurate "diagnosis" for the health status of the equipment, effectively preventing faults, and improving the safety and stability of industrial production.

In the current era of rapid technological development, sensors, as key components for obtaining information, are widely used in many fields such as industry, healthcare, and automobiles. Chinese sensor companies are actively exploring ways to break through and innovate in the global competitive landscape, striving to enhance their competitiveness and achieve leapfrog development.

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.
