Fiber optic collectors represent a technology central to advanced daylight harvesting systems, capturing natural sunlight from exterior environments. These devices utilize optical lenses or parabolic mirrors to concentrate sunlight, directing it into bundles of optical fibers. This review aims to track, an- alyze, and discuss the application of integrated FOD systems with concentrating. In this context, fiber optic daylight (FOD) systems are a growing technology, where fiber optics can be used as a waveguide to transmit sunlight into the interior of windowless spaces. Solar-concentrating systems typically track the sun with mechanical structures but can also be. Fiber optics have enabled everything from light-transmitting concrete to see-through wood, but lately have found even more innovative applications for interior daylighting. Passing through a thin wooden wall or concrete block is one thing – but imagine natural light that could wind its way through.
