Query: Regularized Inverse Holographic Volume Reconstruction for 3D Particle
  Tracking   The key limitations of digital inline holography (DIH) for particle tracking
applications are poor longitudinal resolution, particle concentration limits,
and case-specific processing. We utilize an inverse problem method with fused
lasso regularization to perform full volumetric reconstructions of particle
fields. By exploiting data sparsity in the solution and utilizing GPU
processing, we dramatically reduce the computational cost usually associated
with inverse reconstruction approaches. We demonstrate the accuracy of the
proposed method using synthetic and experimental holograms. Finally, we present
two practical applications (high concentration microorganism swimming and
microfiber rotation) to extend the capabilities of DIH beyond what was possible
using prior methods.
