A single-image nitric-oxide molecular tagging velocimetry (NO-MTV) is reported and employed in a real air driven hypersonic shock tunnel and provided velocities of 3240 170(5.2%) and 3030 160(5.3%) m , insignificantly different from previous results of 3037 98(3.2%) obtained by an ordinary multi-image MTV technique. The proposed methodology relies on an one-dimensional analytical description of the spatial intensity profile registered by a single MTV image.

单图像分子标记测速

报告了单图像一氧化氮分子标记测速仪（NO-MTV），并在实际的空气驱动高超音速冲击隧道中使用，其速度分别为3240 170（5.2％）和3030 160（5.3％）m ，与以前的速度无明显差异普通多图像MTV技术获得3037 98（3.2％）的结果。所提出的方法依赖于由单个MTV图像记录的空间强度轮廓的一维分析描述。
