Subsurface imaging technology to reveal the unseen​

Core Technology

Subsurface Imaging Technology

The term "subsurface" refers to what lies beneath an object's surface. Subsurface imaging technology utilizes scattered waves within an object to analyze and reveal its internal structure and condition. This technique is founded on our pioneering scattered field theory and sophisticated engineering.

Wave Scattering Field Theory

This innovative imaging theory originates from solving the "inverse problem of wave scattering," a challenging issue in applied mathematics.

IGS focuses on developing theories and methods to analyze an object's internal structure. The core methodology involves detecting waves emitted from within an object and using these observations to visualize its internal composition. The critical question addressed is determining the appropriate equations and solutions to reconstruct an object’s 3D structure from surface observations.

In scenarios where an object comprises a medium and regions with differing physical properties, and these properties are known, the observed signals can be predicted using fundamental physics equations. However, if the object’s properties are unknown, the process involves reversing the typical causal relationships in physics to infer these properties from the observed data.

Key Considerations in Reverse Causal Analysis in Physics

When tracing causal relationships in physics in reverse, the following three aspects are crucial:

  1.  The establishment of a robust mathematical foundation, akin to that used in the corresponding forward problem.
  2. The electrical and mechanical setup of the observation system must be adaptable yet stable across varying measurement conditions.
  3. The availability of an efficient algorithm capable of performing computations within a reasonable timeframe on standard commercial computers.

Under these conditions, we achieved a global first by analytically solving the inverse problem of wave scattering—a longstanding challenge in applied mathematics. This breakthrough, known as the "Scattering Field Theory/Inverse Analysis Theory of Wave Scattering," involves using wave irradiation and observation of the scattered waves to theoretically ascertain an object's internal structure. We derive and solve multidimensional partial differential equations representing the scattering field, using observed results as boundary conditions to expose the object’s internal architecture through temporal and spatial limit operations.

IGS Solutions and Analytical Theories for Inverse Problems

IGS technology is underpinned by more than just the "Scattering Field Theory/Inverse Analysis Theory of Wave Scattering." Recognizing the necessity for innovative fundamental theories to develop new solutions, we are committed to continuous research in this area.

We have derived the mathematical equation that governs all phenomena of wave scattering. This equation enables the instantaneous reconstruction of an object's 3D structure through scattered wave ripples. It is fair to say that the potential applications of this discovery are boundless.
