Fresnel Lenses replace the curved surface of a conventional lens with a series of concentric grooves, molded into the surface of a thin, lightweight plastic sheet. The grooves act as individual refracting surfaces, like tiny prisms when viewed in cross section, bending parallel rays in a very close approximation to a common focal length. Because the lens is thin, very little light is lost by absorption. Fresnel Lenses are a compromise between efficiency and image quality. High groove density allows higher quality images, while low groove density yields better efficiency (as needed in light gathering applications). In infinite conjugate systems, the grooved side of the lens should face the longer conjugate. Fresnel lenses are most often used in light gathering applications, such as condenser systems or emitter/detector setups. Fresnel lenses can also be used as magnifiers or projection lenses; however, due to the high level of distortion, this is not recommended.

Polymer optical fiber has significant advantages, including flexibility, durability, lightweight, biocompatibility, and electromagnetic interference immunity. It can not only be used as a single sensor probe but also be integrated into fabric as smart textiles. This chapter presents a review on structures, types, materials, and physical properties of POF; current technologies applied in POF sensors; applications of POF sensor; and POF in textiles. Finally, the current issues in this area are discussed.
