Polarization

▸Polarization refers to separating light according to its orientation or polarity. 
In other words, it selectively filters light so that only the desired polarization component is received.
▸Insects with compound eyes are capable of detecting polarized light, whereas humans can perceive only the brightness and color of visible light and cannot detect polarization information.

Product Overview
​
Conventional CCTV cameras often struggle to capture clear and accurate images in environments with strong reflected glare, such as coastal areas, sunset-exposed locations, and rain-soaked roads.

Expected Benefits

  • Technical Benefit
  • Economical Benefit
  • Policy Benefit
• Compared with conventional methods such as manual replacement of polarization filters or mechanical control of polarizing plates using motors, this technology offers easier installation and maintenance of polarization filters.
• By adopting an innovative electrical polarization control technology with no mechanical failure risk, it enhances competitiveness in both domestic and global markets.
• Delivering significantly clearer images than conventional CCTV cameras, it provides an optimal solution for a wide range of applications.
• It is highly effective for monitoring various objects and environments where diffuse reflection occurs, including sea surfaces, glass surfaces, icy or rain-soaked roads, tunnels, vehicles, and facilities.
• In addition to outdoor environments, it can also be applied indoors to object recognition fields requiring the elimination of reflected glare, such as product inspection, assembly lines, and worker safety.
• As the technology can be implemented through the retrofit of existing CCTV cameras, previously installed and operating video surveillance systems can be reused, thereby preventing unnecessary waste of national budget.
• Because the polarization effect is achieved through the electrical control of LCD elements, it is less prone to mechanical failure than conventional manual filter replacement or mechanical filter rotation methods. Its ease of installation and maintenance also results in significant savings in manpower, maintenance time, and operating costs after deployment.
• By delivering polarization control optimized for the imaging characteristics of each application, it provides tailored solutions for a wide range of industry-specific needs.
• Suitable for deployment in intelligent video monitoring systems for smart cities
• Can be utilized for the development of AI training big data and video learning datasets
• Applicable across related sectors, including public safety, smart cities, security surveillance, autonomous driving, drones, and robotics
• Can be applied to traffic management systems by detecting wet and icy road conditions on highways, helping to prevent accidents caused by black ice
