High Knudsen number flows such as highly rarefied gas flows with large mean free path and gaseous flows around nano-devices with small characteristic length have become more important. In this letter, I introduce mainly the diagnostic techniques for the high Knudsen number flows, such as laser induced fluorescence (LIF), resonantly enhanced multiphoton ionization (REMPI) and pressure sensitive molecular film (PSMF), and our experimental results obtained by the use of the techniques.
