Patent number: 8107061Abstract: In a schlieren optical system, a laser beam is passed through the jet flow and the ambient around the jet flow, and a high speed sampling is performed using a high speed photo sensor while displacing measurement points. The value obtained by sampling represents a result of the optical path caused curved by a density gradient generated in an arc-shape from the center of the jet flow. The value is subjected to a high speed discrete Fourier transform and decomposed into frequency components which constitute the noise. Thereafter, Abel inversion is performed on data belonging to a particular frequency to obtain a density gradient in the radial direction from the center of the jet flow. The obtained density gradient is visualized in a graph display, so that the position of the sound source and the state of the jet flow can be accurately grasped.Type: GrantFiled: January 8, 2010Date of Patent: January 31, 2012Assignees: National University Corporation Gunma University, Japan Aerospace Exploration AgencyInventors: Mikiya Araki, Yusuke Sone, Takayuki Kojima, Hideyuki Taguchi, Seiichi Shiga, Tomio Obokata
