This study examines three advanced optical sensing systems, such as NIR spectroscopy, RGB imaging with computer vision, and NIR-HIS for precision food drying, discussing their mechanisms, applications, and integration with traditional techniques.

The optical sensor market is classified into type, sensor type, end-user, and region.

Type

The target market is be divided into types, including intrinsic, extrinsic sensors, and others. The intrinsic optical sensors dominated the optical sensor market as it can, if required, provide distributed sensing over distances of up to 1 meter. It can also be used to measure physical quantities, such as, pressure, temperature, and strain.

• For instance, in February 2024, according to the article published by Research Gate, a distributed optical fiber sensor (DOFS) is an intrinsic sensor that was able to determine the spatial distribution of one or more measured parameters at each and every point along with a sensing fiber. DOFS have gained widespread usage, and it serves as a fundamental component in smart sensing systems and plays a crucial role in smart cities.

Sensor Type

Fiber optic, photoelectric, optical temperature sensors, and others are among the types of sensors that make up the optical sensor market. The optical temperature sensors dominated the market share as the increase in the adoption of Industrial Internet of Things (IIoT) technologies and smart manufacturing processes led to a greater demand for temperature sensors.

• For instance, in September 2022, Sensirion expanded its selection of temperature sensors with the addition of the digital automobile sensor STS4xA. There were two variants of the STS4xA series, including STS41A-AD1B and STS41A-AW1B. The latter supported automated optical inspection (AOI) by providing optional wettable flank packing. Additionally, improved on-board diagnostic (OBD), which was made possible by the embedded on-chip heating, allowed for a functionality and plausibility diagnosis to be performed rather than only a presence check.

End-User

Healthcare, consumer electronics, energy and utilities, aerospace and defense, automotive and transportation, manufacturing, and other industries are the end-user-based categories for the target market. The consumer electronics holds the dominant optical sensor market share due to the versatility and applicability in various devices, such as smartphones, Smartwatches, cameras, and augmented reality (AR) devices.

Region

Based on region, the optical sensor market can be categorized into North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa.

Asia-Pacific: Asia Pacific is dominating the market during the forecast period, as it has an enormous and massive market for any company which manufactures smartphones. This market or industry is skyrocketing in countries, such as India and China, with fierce competition between companies, such as, Apple, Samsung, Vivo, Oppo, Xiomi, and others.

• For instance, in September 2024, the 10^th Asia-Pacific Optical Sensors Conference, was hosted by UESTC. The conference set a total of 10 themes which were distributed optical fiber sensor, micro-nano structure sensor, biochemical sensor, laser sensor, photo-acoustic sensor, sensing fiber, sensing optical device, sensing demodulation instrument, optical sensing application, and optical sensing industrialization, covering the mainstream development direction in the field of optical sensing. This conference shed light on how the field of optical sensing is rapidly advancing, with cutting-edge research results reported in the latest Nature/Science papers, and the successful listing of multiple companies.

North America: This region is estimated to grow at a higher rate during the forecast period, compared to the other regions due to the constant product innovation and development, such as advanced safety systems and vehicle technology, road safety, adoption of smartphones, electric vehicles and smart home applications, and others, keeping the demand of optical sensors high in the U.S. Market.
