摘要: The physical optics of the laser-schlieren technique for measurement rate processes in shock waves is examined detail. method utilizes Kirchhoff-Huygens integral with usual thin lens, paraxial, and Fresnel approximations, all which are appropriate typical laser schlieren experiment. resolution sensitivity defined detector separations, a reliable locating time origin signal provided. Diffraction found to have significant effect on front generated signal, geometrical treatments this shown be inadequate.
