QHYCCD supports a variety of multi-sensor mosaic configurations based on project requirements. Through precision mechanical design, advanced assembly processes, and accurate calibration, multiple sensors are precisely aligned and securely integrated to ensure stable performance and provide a reliable foundation for subsequent image stitching and data processing.
Different CMOS sensors with various formats and pixel sizes can be selected according to application requirements, allowing the imaging system to be optimized for specific projects.
To accommodate the large data volume generated by multi-sensor imaging systems, QHYCCD offers multiple high-speed data interface options, including:
Combined with QHYCCD’s proprietary data acquisition and control platform, the system supports synchronized multi-sensor image acquisition, high-bandwidth data transfer, and stable long-term operation for high-resolution, high-frame-rate imaging applications.
Depending on the application, the camera can be equipped with a high-performance thermoelectric cooling (TEC) system together with air or liquid cooling solutions for efficient thermal management.
Effective sensor cooling reduces dark current and thermal noise, improving image quality during long-exposure operation and ensuring stable performance in demanding scientific and industrial environments.
QHYCCD provides complete custom development services for CMOS mosaic cameras, including:
From concept design and prototype development to final system delivery, QHYCCD provides comprehensive engineering support throughout the entire project.
CMOS mosaic camera solutions are suitable for a wide range of applications, including:
QHYCCD has extensive experience in developing large-format CMOS mosaic cameras. A typical example is a 2 × 2 mosaic camera integrating four CMOS sensors, which combines high-precision sensor alignment, high-speed data transmission, and an efficient cooling system to achieve ultra-large-format scientific imaging for astronomy, remote sensing, industrial inspection, and other high-performance imaging applications.
To meet the requirements of a large-format scientific imaging project, the customer specified the following key sensor requirements:
Based on these requirements, QHYCCD selected the Sony IMX411 CMOS sensor and developed a 2 × 2 mosaic camera integrating four sensors into a single imaging system.
The IMX411 features an active imaging area of 53.4 mm × 40.0 mm. Considering the sensor package dimensions (75 mm × 63.6 mm) and assembly tolerances, the complete 2 × 2 sensor assembly measures approximately 150.7 mm × 127.9 mm.
Through optimized mechanical layout and high-precision sensor alignment, the effective imaging area occupies approximately 44.4% of the overall sensor package, achieving an efficient large-format mosaic while maintaining the mechanical stability required for scientific imaging applications.
The system combines:
to deliver ultra-large-format, high-resolution imaging for applications including astronomical observation, remote sensing, and industrial inspection.
The figure below shows the overall layout of the 2 × 2 IMX411 mosaic sensor assembly.
