Optical Coherence Tomography (OCT) Firmware

Precision OCT Signal Processing Powered by FPGA DSP

Accelerate imaging performance with Optical Coherence Tomography (OCT) Firmware engineered for GaGe FPGA digitizers—designed to deliver unmatched accuracy, speed, and control in your most advanced medical, scientific, and industrial OCT applications. This intelligent solution captures optical spectra in real time and solves the challenges of nonlinear frequency chirps, inactive clock signals, and signal distortion with patented virtual external clocking. Eliminate the need for host-side correction algorithms and gain total control over clock management and signal synchronization. Whether you’re advancing biomedical research or refining non-destructive testing, this firmware empowers you with smarter, faster optical data acquisition and processing.

Built for engineers and researchers working on high-speed optical DSP, OCT firmware, and FPGA digitizer integration, this solution ensures synchronized acquisition of both interferometer and returned optical signals—creating a reliable data foundation for precise spectral analysis. Say goodbye to manual corrections and inconsistent sampling and experience the power of optical FPGA processing built for real-world performance.

  • Advanced Virtual External Clocking:
    Simulate precise external clocking in the digital domain without relying on inconsistent k-clock inputs—ideal for nonlinear optical pulses.
  • Simultaneous Dual-Channel Digitization:
    Capture both the k-clock (interferometer) and optical detector signals at once using dual-channel FPGA digitizers.
  • Robust Clock Management:
    Reject low-amplitude rising edges and manage boundary clock transitions with full control over raw data sample numbers.
  • Precision FPGA Signal Processing:
    Apply high-resolution interpolation to localize rising edges with sub-nanosecond accuracy for ultra-precise OCT reconstruction.
  • Real-Time Spectral Acquisition:
    Capture and convert time-domain signals into clean, usable optical spectra even from chirped, non-linear laser sources.
  • No Host CPU Load:
    Offload all processing to the FPGA hardware, keeping your host system free for visualization, storage, or additional computations.
  • Streamlined Integration with SDKs:
    Use the included GaGe SDK for C/C# to deploy compiled OCT sample programs with documentation for custom development.
  • Optimized for Optical DSP Applications:
    Tailored for biomedical imaging, ophthalmology, spectroscopy, and materials inspection that rely on consistent and high-speed data acquisition.
