Technology Transfer Opportunity Projected BackgroundOriented Schlieren Imaging LarTops365 Description NASAs Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize manufacture and market the following technology License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use NASA provides no funding in conjunction with these potential licenses THE TECHNOLOGY Inventors at the NASA Langley Research Center LAR have developed a new backgroundoriented schlieren BOS imaging technique The new technique enables vibrationtolerant realtime and referencefree BOS imaging for scientific investigations or industrial flow monitoring Typically BOS imaging requires a physical pattern on a retroreflective surface within the flow of interest to visualize that flow through changes in the pattern due to density changes between the pattern and a camera Here the BOS imaging technique does not require a physical pattern within the flow and it is instead projected through the flow onto a retroreflective surface that is then imaged by a camera Projecting the pattern allows the pattern to be changed midmeasurement and may lessen the cost of BOS imaging for a variety of flow visualization applications The Projected BOS imaging system developed at the NASA Langley Research Center provides a significant advancement over other BOS flow visualization techniques Specifically the present BOS imaging method removes the need for a physically patterned retroreflective background within the flow of interest and is therefore insensitive to the changing conditions due to the flow For example in a wind tunnel used for aerodynamics testing there are vibrations and temperature changes that can affect the entire tunnel and anything inside it Any patterned background within the wind tunnel will be subject to these changing conditions and those effects must be accounted for in the postprocessing of the BOS image This postprocessing is not necessary NATIONAL AERONAUTICS AND SPACE ADMINISTRATION Contracting Office Address HOUSTON TX 77058 HOUSTON TX 77058 USABR Primary Point of Contact Kathryn Taylor kathryntaylornasagov Phone Number 2814832361BR Secondary Point of Contact Karen Dailey karenjdaileynasagov Phone Number 2814833445 agencypatentlicensingmailnasagov Tender Notice International Competitive Bidding T2PLaRC00121 United States of America GT90384449
