NIST is seeking a large area solar simulator to overcome the shortcomings of current solar simulators. To meet this need, Physical Optics Corp. (POC) proposed to develop a new Holographic Light-Emitting-Diode-Based Solar Simulator (HOLIOS) based on holographic gratings, holographic diffuser, high-power light emitting diodes with electronic drivers, collimating and projection optics, and photodetectors for monitoring output. HOLIOS can accurately simulate both solar irradiance under a wide range of air mass conditions, and atmospheric absorption by water, oxygen, ozone, and carbon dioxide molecules. It can irradiate a 1.5 m by 1.5 m area at irradiance levels that can be varied from <500 to 1300 w/sq. m, and the uniformity of the irradiance level among measurement blocks will be tunable within +/-2% over the 2.25 sq. m area. In Phase 1 POC will build a deliverable small-scale HOLIOS prototype capable of illuminating an area > 30 cm x 30 cm and of meeting all NIST requirements. COMMERCIAL APPLICATIONS: The proposed solar simulator not only addresses NIST requirement for a large-area solar simulator that overcomes the shortcomings of current solar simulators, but also has significant commercial applications in agriculture -- for artificial greenhouses in remote locations such as the arctic and space stations -- and in treatment of skin disorders.
