Latest Patents

Hofer holds a patent for a "Luminescent security feature and method and device for examining it." This invention involves a security feature that consists of multiple luminescent surface elements, each with varying luminescence lifetimes. To verify the security feature, a lock-in imager is employed. The feature is illuminated with excitation light that is intensity-modulated at a specific frequency. The emitted luminescent light is then detected synchronously with this modulation frequency across various pixels. This process allows for the determination of a phase shift between the excitation light and the luminescent light, which is crucial for verifying the security feature.
