The Frontier of Multimodal Data Acquisition
The Spectral Imaging Room (SIR) is a specialized 54 m² facility added to the IXR Platform designed for high-precision, multi-source digital capture. By combining hyperspectral imaging, 3D topography, and high-resolution colorimetry, the SIR provides a comprehensive environment for material analysis, cultural heritage digitization, and industrial inspection research.
The RETURN Multimodal Capture System
At the heart of the SIR is the RETURN system, a state-of-the-art, conveyor-based scanning platform designed for the seamless co-registration of diverse data types.
Engineering Precision
The system relies on a custom-designed 6,500 mm conveyor with a usable width of 475 mm. To ensure « pixel-perfect » data fusion, the bench is engineered for extreme stability:
- Speed Control: Variable up to 1 m/s.
- Dimensional Stability: Deflection remains less than 0.5 mm even under load.
- Geometric Integrity: This stability is critical for the « push-broom » acquisition method, enabling the reconstruction of coherent 2D images and the precise superimposition of 3D data onto hyperspectral cubes without distortion.
Integrated Linear Sensors
The RETURN system captures data line-by-line using four high-performance sensors:
- 3D Profilometer: Line laser triangulation sensor (4,080 pixels/line) for high-resolution relief mapping.
- Color Camera (HIK): MV-CL043-A1GC (4096 x 3 R,G,B pixels/line) for ultra-sharp chromatic detail.
- Hyperspectral VNIR (Specim FX10): 1024 pixels/line across 224 bands (400–1000 nm).
- Hyperspectral SWIR (Specim FX17): 640 pixels/line across 224 bands (900–1700 nm).
Matrix & Portable Imaging
Beyond the linear conveyor system, the SIR is equipped with matrix sensors for versatile, area-based acquisition:
- SILIOS TOUCAN: A multispectral MFA (Multispectral Filter Array) camera for real-time spectral snapshots.
- Specim IQ: A portable, handheld VIS/NIR hyperspectral camera, ideal for in-situ measurements and rapid prototyping.
Light & Material Characterization
To ensure the scientific validity of our captures, the SIR includes a suite of precision measurement devices used for calibration and optical characterization:
| Device Category | Model | Capabilities |
| Spectrocolorimeters | xRite EyeOne (1, 2, and 3) | Precision color management and surface profiling. |
| Spectroradiometer | Jeti 1511 NIR | High-accuracy light source measurement in the NIR range. |
| Spectroradiometer | Jeti Specbos 2501 | Comprehensive UV/VIS/NIR analysis. |
Use Cases & Research Applications
The SIR is uniquely positioned to handle complex projects requiring Data Fusion:
- Material Analysis: Identifying chemical compositions via SWIR/VNIR.
- Surface Metrology: Correlating 3D texture with spectral signatures.
- Digital Twins: Creating high-fidelity, interactive models of physical objects with accurate optical properties.
