Optical Sensing Market Trends

Growth Drivers

• Miniaturization revolution in consumer and medical electronics: A key factor fueling the market growth is the continuing miniaturization of optical sensors, which is enabling them to be integrated into the next generation of small and powerful consumer and medical products. In a ground-breaking development, SCIVAX and TSLC joint-ventured in April 2025 to create the world's smallest Photoplethysmography (PPG) sensor head for vital signs monitoring. One-tenth the size of conventional devices, this innovation opens the way for more discreet and sophisticated health monitoring in wearables like smartwatches and fitness bands, providing new possibilities for personal and remote healthcare.

• Development of AI-driven machine vision and automation: AI-driven, high-speed inspection systems are in high demand since manufacturers prefer more efficiency and quality control. In April 2023, Cognex released its In-Sight 3800 vision system, with edge learning capability for high-speed inspection on high-speed production lines. The trend has deep connections to the development of robotics, with a report by the International Federation of Robotics (IFR) revealing that China's production of industrial robots rose by 17% in the first half of 2024 alone.

• Technological developments in cars and Advanced Driver Assistance Systems (ADAS): The auto sector's rapid advancement towards enhanced safety and autonomous driving features has transformed it into a significant consumer of high-performance optical sensors. The sensors are critical to a broad suite of Advanced Driver Assistance Systems (ADAS), ranging from lane-keep assist to pedestrian detection. In November 2024, onsemi revealed that its Hyperlux AR0823AT image sensor was chosen by Subaru for its next-generation EyeSight stereo-camera front sensing system. This inroad by high-performance optical sensors into high-volume vehicle platforms is a strong and persistent market growth factor.

Challenges

• Improving performance in challenging environments: A critical challenge for the optical sensing industry is to deliver high reliability and performance in harsh ambient conditions, such as extreme brightness or challenging surface conditions. Traditional sensors may not necessarily be capable of gathering reliable data in these conditions, limiting their application. Overcoming such hurdles entails the application of advanced solutions that can cope with variations of light and surface texture. Designing rugged sensor technologies that can eliminate noise and maintain signal integrity is the answer. This is likely to enable broader use of optical sensing in industrial and business applications.

• Overcoming physical and environmental difficulties: Optical sensors are destined to face inherent physical limitations upon implementation in particular media, such as water, that cause blurriness and distortion, reducing image quality. Besides, external environmental factors such as extremely high or low temperature or pressure also affect their functioning and usability. These limitations are destined to necessitate advanced workarounds or make optical sensors unavailable in certain challenging scenarios. Countermeasures that can overcome these inherent limitations must be developed to enhance sensor technology and expand its applications in various sectors.
