Overview
The Hamamatsu C9750-27FCC and C9750-27FCD are high-performance C-geometry line-scan X-ray cameras engineered for industrial non-destructive testing (NDT), with primary application in radial tire inspection systems. These cameras operate on the principle of time-delay integration (TDI) coupled with scintillator-based indirect detection: incident X-rays are converted to visible light via a Gd2O2S:Tb or CsI:Tl scintillator layer, then focused onto a high-sensitivity linear CCD sensor array using precision optical coupling. The C-shaped mechanical configuration enables optimal geometric alignment between the X-ray source, rotating tire under test, and detector—minimizing parallax error and maximizing spatial fidelity across the full 3456-pixel active line. Designed for continuous motion imaging, the camera achieves sub-pixel gap coverage (<1 pixel residual gap) over a full 360° tire rotation, ensuring seamless, stitch-free volumetric reconstruction of tread, belt, and carcass layers.
Key Features
- C-geometry mechanical architecture optimized for inline tire NDT systems, supporting source-to-detector distances compatible with standard industrial X-ray generators (100–150 kVp range)
- 3456-pixel linear CCD sensor with TDI capability for enhanced signal-to-noise ratio (SNR) during high-speed rotational scanning
- High quantum efficiency (>65% at 40 keV) enabled by optimized scintillator thickness and spectral matching to CCD spectral response
- Dynamic range exceeding 70 dB, supporting simultaneous visualization of low-density rubber compounds and high-attenuation steel cord structures
- Programmable gain and offset control for adaptive contrast optimization across varying tire constructions (e.g., all-season vs. ultra-high-performance)
- Industrial-grade housing rated IP54, with thermal stabilization circuitry to maintain dark current stability over extended acquisition cycles
Sample Compatibility & Compliance
The C9750-27FCC/FCD is validated for use with passenger car, light-truck, and commercial vehicle tires up to 32 inches in diameter. Its mechanical envelope accommodates standard tire mounting chucks and supports integration into ISO/IEC 17025-accredited NDT laboratories. The system complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) standards. Data acquisition workflows align with ASTM E2737-21 (Standard Practice for Digital Radiographic Testing of Tire Components) and support traceable calibration per ISO 17025 requirements. Optional firmware modules enable audit trail logging required for GLP/GMP environments.
Software & Data Management
Hamamatsu provides the ORCA-Flash SDK v5.x for native integration with custom inspection platforms (C++/C#/Python APIs). The camera supports GenICam-compliant metadata embedding—including exposure time, TDI stage count, and temperature-compensated gain settings—enabling automated DICOM-SR generation for PACS-compatible archiving. Raw 16-bit TIFF sequences are output via Camera Link HS interface (8-lane configuration), with real-time frame buffering up to 4 GB onboard. All firmware updates undergo rigorous regression testing against USP analytical instrument qualification (AIQ) protocols.
Applications
- Automated detection of steel belt misalignment, splice gaps, and ply separation in radial tires
- Quantitative assessment of tread compound homogeneity and void distribution
- In-process quality verification during final assembly of OEM-specified tire builds
- Root cause analysis of field failures through comparative microstructure imaging
- Research-grade characterization of novel composite reinforcement architectures (e.g., aramid hybrid belts)
FAQ
What distinguishes the C9750-27FCC from the C9750-27FCD variant?
The C9750-27FCC features a fiber-optic taper input window for higher spatial resolution preservation; the C9750-27FCD uses a lens-coupled configuration optimized for higher light throughput in lower-dose applications.
Is this camera compatible with third-party X-ray generators?
Yes—provided the generator offers stable pulsed or continuous emission with TTL synchronization capability and operates within the 80–150 kVp range.
Does Hamamatsu provide calibration services for this model?
Yes—NIST-traceable flat-field and linearity calibration reports are available as part of the factory acceptance test (FAT) package, with optional annual recalibration under ISO/IEC 17025 scope.
Can the camera be integrated into a Linux-based inspection platform?
Yes—the ORCA-Flash SDK includes POSIX-compliant drivers and sample code for Ubuntu 20.04 LTS and later, with full support for multi-threaded acquisition pipelines.
What is the maximum recommended scan speed for full-resolution imaging?
At 3456 pixels and 16-bit depth, sustained line rates up to 12 kHz are achievable with appropriate cooling and host bandwidth; typical tire inspection setups operate between 4–8 kHz depending on required SNR and spatial sampling density.
