Latest Patents

One of Erqiang Li's latest patents is titled "Rainbow Particle Imaging Velocimetry for Dense 3D Fluid Velocity Imaging." This invention allows for the imaging of complex, non-stationary three-dimensional (3D) flow velocities by encoding depth into color. The flow volume is illuminated with a continuum of light planes, where each depth corresponds to a specific wavelength of light. A diffractive component in the camera optics records the trajectories of illuminated particles within the flow volume, ensuring that all light planes are in focus simultaneously. This setup enables users to track 3D trajectories of particles by combining two-dimensional (2D) spatial and one-dimensional (1D) color information. For reconstruction, an image formation model is provided to recover stationary 3D particle positions. The 3D velocity estimation is achieved using a variant of a 3D optical flow approach that considers both physical constraints and the color image formation model.
