Sensors in the chip, 5G, 6G communication technology, artificial intelligence, automatic driving industry has been widely used, "Liaoning" "Shandong" aircraft carrier, type 093 attack nuclear submarine, type 094 ballistic missile nuclear submarine, type 055 missile destroyer, J-20 fighter jet... And so on, all kinds of photoelectric, infrared, inertial navigation sensors.

Intercontinental ballistic missiles such as the DF-31A, DF-41, and DF-5B, as well as various other guided weapons, rely on inertial measurement units (IMUs), laser sensors, infrared sensors, millimeter-wave sensors, photoelectric sensors, radar and other sensors for guidance to accurately hit targets.

In recent years, the hot automatic driving technology, no matter what kind of program, at least need to use cameras, millimeter-wave radar, ultrasonic radar, Lidar and other sensors for information perception. A mobile phone has 10+ sensors in it, a car has 300+ sensors, a high-speed train has 2400+ sensors... In manufacturing, in artificial intelligence, in the Internet of Things, Sensors are everywhere.

From the perspective of technology and application type, sensors are divided into temperature, pressure, ultrasonic, flow, resistance, image sensors, etc. From the perspective of disciplines, including sound and electricity, sensors are also divided into chemical, physical, biological sensors, etc.; From the perspective of industrial layout, it is divided into consumer grade, automotive electronics, industrial grade, and medical sensors.

In terms of consumer electronics, automotive electronics, medical electronics and high-end industrial manufacturing, the domestic sensor market accounts for no more than 10%, which has become the industry consensus.

Shenzhen Liyi Technology Co., Ltd. has carefully developed and created spectral confocal displacement sensors with advantages of high precision, high stability and high universality, which add help to break the dilemma of China's manufacturing industry.

The spectral confocal displacement sensor of Vertical instrument technology can easily deal with the measurement of metal, glass, mirror body, black rubber, ceramics and other materials, and the accuracy can be stably maintained within 1um, with high precision linear performance on various materials, relative to the traditional triangle laser displacement sensor, in the domestic precision measurement field achieved a new breakthrough. In practical applications, spectral confocal displacement sensors have also won high recognition by virtue of their distinct advantages such as high precision, high stability and high universality.

In addition, the spectral confocal displacement sensor can also be used in panel display, dispensing, measurement and other fields, such as smart device LCD panels, precision non-contact measurement, and panel electrode thickness measurement. In areas critical to people's livelihood such as transportation, new energy, and medical care, spectral confocal displacement sensors can also play an auxiliary role to help aircraft, high-speed rail, batteries, glass containers, and other manufacturing finer and better.
