Flexible optics is a research field focused on the design, fabrication, and application of optical components and systems that can intentionally deform or change their physical shape. This concept investigates materials science, mechanical engineering, and optical principles to create adaptive lenses, mirrors, waveplates, and other elements offering reconfigurability, dynamic wavefront control, and enhanced robustness. Its significance lies in enabling novel functionalities for imaging, sensing, and illumination systems, often facilitating miniaturization and adaptability in diverse environments.
