Advanced Materials and Technologies

When it comes to the formation of controlled patterns of light, the employment of refractive free form components is becoming an increasingly significant component. This is due to the fact that these components have the ability to spatially modulate optical signals while maintaining high efficiency and a minimum background. Despite this, the use of these devices is limited due to a number of problems that need to be resolved. When it comes to the manufacturing of macroscopic items that have complicated surface reliefs in Three Dimensions (3D). This study discusses “magic windows,” which may be 3D-printed on flexible material and form light patterns via the process of refraction.
