Color-Changing, Holographic Fresnel Lenses Made Possible with

3D printing makes manufacturing regular lenses, and more recently Fresnel lenses, easy and cost-efficient, but now, additive manufacturing can be used to extend their functionality with enhanced optical properties and sensing abilities.     A Khalifa University research team has used additive manufacturing techniques to develop five-dimensional Fresnel lenses, incorporating color-change phenomena and holographic diffraction effects. … Continue reading "Color-Changing, Holographic Fresnel Lenses Made Possible with Additive Manufacturing"
