Density Field Reconstructing in the Supersonic Wind Tunnel Using OCT Technology

In the researches of the flow visualization of supersonic flow field, there are large numbers of interference stripe pictures which needed to be dealt with to acquire the necessary results of aero-optics effects. Especially in three-dimensional non-contact measurement which are crucial for the modern high-tech aerodynamic and heat transfer field such as modern aviation, aerospace, and energy, the researchers use pulses of laser technology and holographic technology to realize multi-directional projection data acquisition. Then with the help of advanced computing technology and tomography reconstruction technology, optical tomography technology has become an important means of the supersonic flow field visualization study.
