A waveguide array is a group of waveguides arranged together. Each waveguide directs light through a material, and the array can collect spatially distributed signals that help reveal changes across a surface, such as bending, twisting, or orientation.
In cyber security, sensor data from a waveguide array can be an input to systems that monitor devices, environments, or user interactions. Its accuracy and reliability matter: noisy or manipulated measurements could lead to incorrect downstream decisions. In real deployments, protections may include validating sensor readings, checking for unexpected patterns, and securing the data path from the sensing hardware to the software that interprets it.
