I. Sony Ultraviolet (UV) Image Sensors: Breaking through the limitations of visible light to unlock UV imaging capabilities

1. Technical Principles and Core Architecture

The pixel structure, optical lenses and filter layers of traditional CMOS image sensors block light in the UV spectrum, making UV imaging impossible. Sony’s UV image sensors are specifically optimised for the 200nm–400nm ultraviolet spectrum. Departing from the conventional optical design of traditional sensors, they utilise proprietary UV-transmissive materials, a specialised light-receiving unit structure and a back-illuminated pixel architecture, combined with a quartz glass optical window. This significantly enhances UV transmittance and photoconversion efficiency, whilst simultaneously suppressing imaging noise in the UV spectrum, enabling the precise capture of UV light signals that are imperceptible to the human eye and conventional devices.

Furthermore, this series of sensors incorporates Sony’s proven Pregius S global shutter technology, which resolves the ‘jelly effect’ associated with traditional rolling shutter capture of moving objects. This enables high-speed, distortion-free dynamic imaging in the UV spectrum, combining the two core capabilities of high UV sensitivity and high-speed imaging.

2. Core Technical Advantages

- Full UV spectrum compatibility: Covers the entire UV spectrum (UVA, UVB, UVC), overcoming the limitations of visible light imaging to capture UV characteristic information in microscopic and specialised scenarios;

- High image quality with low noise: A customised pixel photodiode structure optimises UV light reception efficiency, significantly reducing short-wavelength imaging noise to achieve clear imaging in low-UV environments;

- High-speed, distortion-free imaging: A global shutter architecture precisely captures fast-moving objects, making it suitable for industrial dynamic detection scenarios;

- High pixel count and high precision: The commercial flagship model achieves tens of millions of effective pixels, balancing imaging resolution with detection accuracy.

3. Representative Products and Application Scenarios

The Sony IMX487 is a benchmark product in UV image sensors. As a 2/3-inch industrial-grade CMOS sensor with approximately 8.13 million effective pixels, it leads the industry in pixel specifications among UV sensors of the same size. Integrating a global shutter and back-illuminated process, it is perfectly suited for industrial precision inspection scenarios.

Core application scenarios are concentrated in the fields of industrial precision manufacturing and professional inspection: including UV adhesive curing inspection on circuit boards, defect and scratch detection on glass and films, and microscopic defect screening on semiconductor wafers; corona discharge and arc detection in high-voltage equipment within the power industry; UV spectral analysis and fluorescence detection in scientific research; as well as UV screening for stains and microorganisms in the food and pharmaceutical industries.

II. Sony Polarisation Image Sensor: Capturing Polarisation Information to Reconstruct Optical Imaging Dimensions

1. Technical Principles and Core Architecture

Natural light is unpolarised, whereas light reflected, refracted or scattered from an object’s surface exhibits unique polarisation characteristics; this optical information cannot be captured by standard RGB sensors. Sony’s polarised image sensor incorporates proprietary Polarsens on-chip polarisation technology, innovatively integrating micro-polarisation elements above the photodiodes of each pixel. This eliminates the need for external polarising filters, significantly simplifying the device’s structure.

The sensor employs a four-pixel array design, with four adjacent pixels equipped with polarising filters at 0°, 45°, 90°, 135° angles, enabling the simultaneous capture of four-dimensional polarised light data. Through algorithmic analysis of the light’s polarisation degree, angle and intensity, it reconstructs the material, stress, texture and surface details of an object, overcoming the limitations of traditional imaging which records only the single dimensions of brightness and colour.

2. Core Technical Advantages

- Multi-dimensional optical data acquisition: Beyond brightness and colour, it incorporates an additional dimension of polarisation information, enabling the identification of subtle differences that conventional imaging cannot distinguish;

- High integration on-chip: The integrated design of polarisation elements and pixels eliminates the need for external optical components, resulting in a smaller device size and higher stability;

- Global shutter high-definition imaging: The entire range is equipped with global shutter technology, eliminating motion blur and making it suitable for dynamic industrial inspection scenarios;

- Strong anti-interference capabilities and high recognition accuracy: Effectively suppresses specular reflections and ambient stray light interference, enabling precise defect detection on transparent and highly reflective objects.

3. Representative Products and Application Scenarios

Sony’s industrial polarisation sensors feature high-resolution, high-stability models tailored to mainstream machine vision requirements. Paired with the dedicated XPL-SDKW development toolkit, they enable rapid polarisation data analysis and image processing, lowering the development threshold for customers.

Core application scenarios span industrial inspection, smart vision, security and traffic monitoring, and other fields: detection of scratches, bubbles and impurities on highly reflective objects (metal, glass, lenses); stress distribution detection in films, plastics and glass products; removal of water surface and glass reflections in outdoor scenarios to enhance surveillance image clarity; detection of road obstacles and perception of high-glare conditions for autonomous driving; as well as inspection of textile textures, paintwork imperfections, and microscopic defects in precision components.

III. Sony Event-Driven Vision Sensor (EVS): Breaking Free from the Constraints of Frame-Based Imaging to Achieve Intelligent Dynamic Vision

1. Technical Principles and Core Architecture

Traditional image sensors employ fixed-frame-rate imaging, continuously outputting full-frame image data regardless of whether the scene has changed, resulting in data redundancy, high latency and high power consumption. Sony’s Event-Based Vision Sensor (EVS) adopts a biomimetic imaging mechanism that simulates the human eye’s visual perception logic, abandoning the fixed-frame output mode.

The core principle is that each pixel independently monitors changes in light intensity; only when a pixel detects a change in brightness does it output event data containing coordinates, time and polarity, whilst pixels showing no change generate no data whatsoever. The sensor employs a stacked chip architecture and a 40nm advanced process, integrating the photosensitive layer with the logic processing layer via copper-to-copper bonding technology to achieve pixel-level independent sensing and high-speed data output.

2. Key Technical Advantages

- Ultra-low data redundancy and ultra-high energy efficiency: Only dynamic change data is output, resulting in a significant reduction in data volume compared to traditional frame imaging and a marked decrease in device power consumption, making it suitable for long-duration standby monitoring scenarios;

- Microsecond-level ultra-low latency: Eliminating the need to wait for frame refreshes, pixel changes are responded to and output instantaneously, with latency far lower than that of traditional cameras, enabling precise capture of details in high-speed moving objects;

- High dynamic range and flicker resistance: Suitable for scenarios with strong light, low light, or sudden changes in lighting; effectively suppresses interference from lighting flicker, offering exceptional environmental adaptability;

- High-speed motion capture without motion blur: Capable of handling high-speed motion scenarios without sacrificing frame rate, perfectly resolving issues of blurring and motion blur when capturing fast-moving objects.

3. Representative Products and Application Scenarios

The Sony IMX636 and IMX637 are mainstream EVS sensor models, featuring a 1/2.5-inch format and HD resolution (1280×720). Equipped with industry-leading 4.86μm ultra-small pixels, they offer high integration and a compact form factor, making them highly adaptable for a wide range of lightweight smart devices.

Core applications focus on high-speed motion detection and low-power smart vision scenarios: foreign object detection on high-speed industrial production lines and trajectory tracking of fast-moving objects; real-time dynamic obstacle avoidance for autonomous vehicles and drones; anomaly detection in smart surveillance, enabling unobtrusive standby and snapshot capture of unusual movements; high-speed obstacle avoidance and dynamic environmental perception in robot vision; as well as sports motion capture and high-speed scientific imaging.
