NASA-s 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 background-oriented schlieren (BOS) imaging technique. The new technique enables vibration-tolerant, real-time, and reference-free 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 mid-measurement 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 post-processing of the BOS image. This post-processing is not necessary... - Documents :
