| 摘 要： | 本文详细探讨了以激光作光源将层析法和全息干涉法结合起来用于测量不稳定的三维温度场的方法。文中给出了以平行平面激光作照射光源的层析干涉法的光路系统及由干涉图重建三维温度场的原则。本文所讨论的方法对传递过程中的三维不稳定场,如密度场、浓度场的测量也是适用的。

| Abstract: | A new optical method for the measurement of a three dimensional unsteady temperature field is proposed. In this method, tomography is integrated with holographic interferometry, namely, the measured surfaces in the field investigated are selected by the tomographic technique and the information on the surfaces is recorded by holographic interferometry.The optical system is given and the principle of calculation of the three dimensional temperature field from the interferograms is discussed. The method proposed is also useful for measuring the three dimensional unsteady density field and concentration field. |
