The Airborne Aero-Optics Laboratory (AAOL) seeks to make flight test a viable and affordable experimental tool to advance the scientific foundation for aero-optic effects and explore mitigation schemes involving flow control and adaptive optics. The flight-test component is the most-unique aspect of this program; however, the success in building the AAOL and the interpretation of the data collected in flight heavily depends on the coordinated use of computations, modeling and wind-tunnel testing. The AAOL is a coordinated program that links advanced CFD to wind-tunnel testing, and wind-tunnel testing to flight test. The AAOL team is confronting the critical tasks of conceiving, predicting, tunnel testing and flight testing flow-control mitigation schemes, turret and fairing designs for best aero-optic environment, adaptive optics, beam control and dealing with the challenging environment posed by transonic flight.","PeriodicalId":275054,"journal":{"name":"2012 IEEE Photonics Society Summer Topical Meeting Series","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116995039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While challenges of cost, performance and thermal design are limiting the rate of adoption, LED bulbs are poised to become a large part of the lighting market in the near future. These LED replacement bulbs will be the first wave of solid-state lighting, where combinations of blue LED chips and phosphors generate acceptable white light efficiently, but leave the full electronic potential of LEDs largely untapped. The combination of digitally controlled full gamut light sources, high performance light sensors and new control and communications methods will create what could be called the second wave of solid state lighting, or Smart Lighting. Smart Lighting systems are comprised of illumination technologies that fully utilize the spectral and temporal capabilities of LEDs to provide light, automatically adapt color and intensity to changing illumination requirements, and provide enhanced services beyond simple illumination. Smart Lighting systems will include the ability to measure and control the intensity, color, polarization, and modulation of light to enable this new lighting functionality, including advanced biosensing, highly efficient “illumination grade” displays, therapeutic lighting, visible light communications, and self commissioning illumination systems.","PeriodicalId":275054,"journal":{"name":"2012 IEEE Photonics Society Summer Topical Meeting Series","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115182609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
