ABSTRACT: To deter birds from colliding with solar panels and other reflective surfaces, InnoSense LLC (ISL) will develop mosaic reflective surfaces based on holographic optical elements (MOSAIC-HOE). MOSAIC-HOE will diffuse the light reflected from windows and/or solar photovoltaic panels to deter bird collision. This surface will consist of multiplexed HOEs that control polarization and surface color at every angle of incidence. Light becomes polarized when it reflects off a smooth, dark surface. To approaching birds, this polarized light signifies a body of water. With MOSAIC-HOE, birds will no longer see a safe smooth surface. A narrowband wide angle HOE will allow a large portion of beneficial wavelengths to be transmitted through the HOE to the solar cell as required. In Phase I, ISL will demonstrate feasibility experimentally and also perform theoretical analysis and computer simulation. In Phase II ISL will develop a prototype comprising multiplexed Bragg HOEs for Air Force testing.; BENEFIT: The MOSAIC-HOE coating is commercially attractive because of its use of low-cost materials and fabrication techniques, and its compatibility with state-of-the-art solar panel technology. Since holographic photopolymers are processed with laser and UV light and heating, holographic filters are far more environmentally stable and rugged than multilayer thin film coatings. These coatings can be adapted to a variety of reflective surfaces, including military and commercial buildings, solar power facilities, and turbines.
