CoaXPress Technology Revolutionizes Deep-Tissue Microscopy with High-Speed Imaging
Superior Machine Vision Interface Performance
CoaXPress (CXP) stands as the premier interface in machine vision applications for transmitting video data from cameras to computers. This technology delivers exceptional data transfer speeds reaching 12.5 Gbps through a single coaxial cable. The interface simultaneously provides power, communication, and control capabilities, offering unmatched performance and operational simplicity.
Expanding Beyond Industrial Applications
The remarkable speed and standard cable infrastructure of CXP has attracted interest across diverse sectors. Defense, broadcasting, medical imaging, and life sciences now leverage this technology. Researchers at Lithuania’s Center for Physical Sciences and Technology have developed an innovative optical microscopy technique utilizing CXP. Their Dynamic Full-Field Optical Coherence Microscopy (d-FF-OCM) system presents a viable alternative to conventional Optical Coherence Tomography.
Breakthrough Microscopy System Capabilities
The d-FF-OCM system achieves unprecedented high-resolution, non-invasive imaging deep within biological tissues. This advancement provides crucial capabilities for understanding fundamental biological processes and enhancing clinical diagnostic procedures. The system incorporates a BitFlow CXP frame grabber alongside an extremely bright, incoherent laser-pumped white light source that delivers optimal illumination to biological samples.
Advanced Optical System Configuration
Light transmission occurs through a multimode fiber to the microscope, which connects to an interferometer containing a 50/50 beamsplitter and two 100x oil immersion objectives. Additional system components include a transitional stage with stepper motor, a reference mirror mounted on a piezo stack, an NI DAQ card, and the microscope assembly.
High-Speed Data Acquisition Architecture
Data transfer functionality critically impacts overall system performance. Biological image data capture utilizes an Adimec 2-megapixel CMOS camera managed by a BitFlow Cyton-CXP4 PCIe CoaXPress frame grabber. When researchers connected all four frame grabber links to the camera using separate coaxial cables, they achieved remarkable data transfer rates of 25 Gbps with virtually undetectable latency.
Enhanced Imaging Performance Metrics
The BitFlow CXP frame grabber enables the system to capture 1440 × 1440 resolution images at 500 frames-per-second, representing a significant improvement over typical scanning systems operating at 100 fps. This fivefold increase extends frequency analysis capability from 30-50Hz to 250Hz. The accelerated dynamic process capture generates fluorescence-like contrasted d-FF-OCM images that better separate biological structures for detailed analysis.
Real-Time Data Processing Methodology
Following data transmission to the computer, information undergoes real-time analysis through a customized LabVIEW application. The system colors each pixel according to its relative spectral content and stacks them into layered configurations to create comprehensive RGB images.
Experimental Validation and Future Applications
Testing on ex vivo mouse tissue samples, including liver and small intestines, demonstrated deep tissue high-resolution imaging completely free from coherent artifacts. These superior results highlight the significant value of the CXP interface in achieving extremely fast camera-to-computer transfer rates. Researchers believe the d-FF-OCM system will play an increasingly important role in advancing personalized medicine, enabling earlier and more precise diagnostics, and facilitating deeper understanding of disease mechanisms.
Application Scenario: Medical Research Laboratory
Imagine a biomedical research laboratory studying cancer tissue samples. Using the d-FF-OCM system with CoaXPress technology, researchers can capture high-speed, high-resolution images of living tissue at unprecedented depths. The system’s 500 fps capability allows observation of dynamic cellular processes in real-time, while the absence of coherent artifacts ensures image clarity. This enables researchers to track disease progression at the cellular level and test treatment effectiveness with precision previously unattainable with conventional microscopy systems.
Author’s Insight: The Interface Revolution in Scientific Imaging
The integration of CoaXPress technology represents a paradigm shift in scientific imaging capabilities. While camera sensors and processing algorithms have advanced significantly, the interface bottleneck has often limited practical application. CXP’s ability to deliver both extreme bandwidth and power over standard coaxial cables addresses this fundamental constraint. This technological advancement enables researchers to capture biological processes at their natural timescales rather than being limited by data transfer capabilities. The resulting image quality and temporal resolution open new possibilities for understanding dynamic biological systems that were previously technically inaccessible.
