Multi-Spectral Light Booth

Multispectral Light Booth – Modeling the World One Spectrum at a Time

The imaging world often talks about capturing “real-world conditions,” but very few tools allow engineers to truly recreate them. At Fourier Image Lab, we’ve built a Multispectral Light Booth designed to do exactly that — enabling controlled, programmable reproduction of light across the visible and near-infrared spectrum, up to 1050nm.

We currently offer two distinct versions of the booth:

• One version includes infrared-enabled lighting, powered by 32 independently controlled LED groups spanning both visible and near-infrared bands.

• The other version focuses on high-resolution visible spectrum reproduction, using 26 color channels optimized for color science, camera evaluation, and material studies.

  
  

Both systems are tightly integrated with our custom-built Spectral Modeling software, which allows users to:

• Import real-world spectral power distributions (SPDs)

• Edit or sculpt target SPDs interactively

• Send control signals to the booth for immediate replication

  
  

Each booth communicates directly with either our in-house spectrometers or Konica Minolta CL-500A units, enabling a closed-loop spectral tuning process. Users can measure the light, model or modify it, and verify the reproduction — all in a seamless, feedback-driven workflow.

In addition to manual control, the booth software supports fully automated operation modes, which can sequence lighting states based on time, exposure profiles, or testing protocols. This feature is especially powerful when used in conjunction with our universal frame grabber system: together, they enable image capture and analysis under controlled spectral conditions without human intervention.

This technology forms the backbone of our spectral reproduction pipeline — bridging outdoor spectral capture, digital modeling, and physical light simulation for true-to-nature testing environments.
