Resumen
In this work, we introduce and test a technique to track the movement of objects from computer-generated holographic videos, without the need for reconstruction. To achieve this, we first generated holographic videos of moving 3D objects using a random phase layer-based approach. Then, we analyzed the hologram phase to determine the locations of the optical vortices. We used the core properties of each vortex to track its movement over all the frames of the video, and then establish a relationship between the object and the vortex movement. We also tested the vortex tracking over a pseudo-phase obtained by performing the Laguerre-Gauss transform of the hologram, which enables more precise control over the number of optical vortices that can be tracked. Our proposal was tested with holographic videos generated with one and two objects, using two different hologram generation approaches.
