Portable and low-cost hologram verification module using a snapshot-based hyperspectral imaging algorithm
One of the challenges in differentiating a duplicate hologram from an original one is reflectivity. A slight change in lighting condition will completely change the reflection pattern exhibited by a hologram, and consequently, a standardized duplicate hologram detector has not yet been created. In t...
