WebHolography is the most common anti-counterfeiting technology currently deployed. Holograms generally do not require special equipment for authentication which makes them ideal where thousands, if not millions of items need protection. WebJun 18, 2024 · To our knowledge, there is no alternative to digital holography for all three use cases that satisfies the simultaneous needs for accuracy, measurement field size, lateral sampling, and measurement time. Theoretical Background. The term holography is derived from the Greek word holos, “whole”, and gráphein, “writing”.
