背景导向纹影（BOS）技术是一种可视化技术，可以通过非常简单的实验设置定量测量流场中的密度信息。 BOS技术的原理类似于传统的纹影技术，利用穿过密度梯度的光线的出售。 BOS利用背景，通过图像分析定量测量背景图像的位移。在本报告中，我们提出了使用条纹背景图案的条纹图案背景定向纹影（SPBOS）技术。在JAXA-ISAS超声速风洞中进行了非对称体周围超声速流场的测量，实现了三维定量密度测量。
The background oriented schlieren (BOS) technique is one of the visualization techniques that enable the quantitative measurement of density information in the flow field with very simple experimental setup. The principle of BOS technique is similar to the conventional schlieren technique which exploit the vending of light rays passing through the density gradient. BOS utilize the background and measure the displacement of the background image quantitatively by image analysis. In this report we propose the stripe-patterned background oriented schlieren (SPBOS) technique using striped background pattern. A measurement of supersonic flow field around an asymmetric body is tested at a JAXA-ISAS supersonic wind tunnel to realize the three-dimensional and quantitative density measurement.
