The market exceeds 100 billion yuan to see China's optical sensor four-year plan of action
In recent years, China's industrial research institutions have increasingly adopted advanced technologies such as multi-image fusion, intelligent inspection robots, and bionics to meet the demands of key sectors like military, aerospace, high-end manufacturing, robotics, autonomous vehicles, and smart grids. These innovations include optical sensor technologies, flexible design methods, and other cutting-edge developments that are now gradually entering the market.
Optical sensors have gained significant popularity in fields such as automotive, industrial automation, medical devices, and consumer electronics. They have become a crucial element in intelligent product design, especially in smartphones, smart lighting systems, digital electronics, and smart manufacturing. The advancement of IoT technology has further driven the evolution of optical sensor capabilities.
The Ministry of Industry and Information Technology’s Electronic Information Department recently commissioned industry associations to develop the “China Optoelectronic Device Industry Technology Roadmap (2018–2022).†This roadmap outlines the development status and future plans for light sensors, highlighting their critical role in downstream applications such as the Internet of Things, smart mobile terminals, and intelligent manufacturing.
Globally, the optical sensor market reached 183.6 billion yuan by 2022, with China playing a major role. In 2016, China’s market was valued at 77.8 billion yuan, accounting for 57% of the global total. The market is expected to grow steadily, with a compound annual growth rate of 7% from 2016 to 2022. However, despite this rapid growth, Chinese companies still face challenges due to limited technological capabilities and weak domestic competition.
In the infrared sensor field, several large-scale manufacturers have emerged, with some products meeting domestic needs. However, high-end technology remains a challenge. In fiber optics, while there is growing investment, the variety of products is still limited, and most sales come from system integration rather than standalone sensors.
In image sensors, which hold the largest market share, Chinese companies dominate the lower-pixel segment but struggle in high-pixel CMOS sensors used in smartphones. Major players like Sony, Samsung, and US-based companies control this space. However, recent acquisitions, such as CITIC Capital’s purchase of Howe Technology, signal progress in China’s image sensor development.
Laser, ambient light, and ultraviolet sensors also face similar challenges, with few domestic firms capable of producing competitive products. Foreign companies currently dominate these markets.
China’s sensor industry lags behind global leaders in both R&D and production. Experts estimate a 10-year gap in R&D and a 15-year gap in production technology. While the country has made strides, it still faces significant hurdles in catching up.
Intellectual property is a key factor in global competition. Patent activity in emerging industries has surged, especially in the US, Japan, and South Korea. Domestic companies need to strengthen their IP strategies to remain competitive.
The optical sensor industry requires interdisciplinary expertise, including optics, microelectronics, materials science, and computer networks. It also demands collaboration across the supply chain and investment in both basic and applied research.
Small and medium enterprises (SMEs) in the sector face economic policy challenges. Most government support favors large corporations, leaving SMEs struggling with high costs and limited access to funding.
Looking ahead, the industry aims to focus on new materials and technologies to drive innovation. Companies must align with market needs, invest in R&D, and collaborate with international partners to improve performance and competitiveness.
Improving high-end product quality remains a core goal. While cost advantages help in the low-end market, high-end segments are dominated by foreign firms. As demand grows, Chinese companies may gain more market share through cost efficiency and strategic investments.
Adopting refined management practices is essential for sustainable growth. Streamlining operations, controlling costs, and improving standards will help companies thrive in a competitive environment.
Expanding international cooperation and accessing global markets is another key objective. Companies must seek talent, obtain international certifications, build strong marketing channels, and prioritize customer satisfaction to succeed globally.
By 2022, China aims to significantly boost local brand sales, increase localization rates to over 30%, and ensure product performance matches international standards. Strategic efforts will focus on key areas like infrared and fiber optic sensors, aiming to cultivate leading companies with strong market presence.
Overall, the path to success in the optical sensor industry involves continuous innovation, strategic partnerships, and a focus on both technical and managerial excellence. With the right approach, China can continue to close the gap and establish itself as a global leader in this rapidly evolving field.
