In this study, we demonstrate the two-tier manipulation of holographic information using frequency-selective metasurfaces. The results show that these devices efficiently diffract light at designed frequency and environmental conditions, enabling the production of two different holographic images by changing the frequency and refractive index of the surrounding environment. These environmental dependent, frequency-selective metasurfaces are expected to have practical applications in holographic encryption and sensing.
