ESPI can measure the object, through forming a carrier pattern on the object surface (carrier pattern modulation), analyze the relation between displacement field and altitude of the object surface.───斑干涉测量技术通过在被测物体表面产生干涉条纹(载频调制条纹),分析位移场与物面高度之间的关系,可测量物面的形貌。
By analyzing the direct frequency modulation and optical feedback effect of laser diode, a theoretical model for measuring small vibration displacement and velocity is discussed.───分析了在直接频率调制下,激光二极管中的光反馈效应,探讨了振动微小位移和速度的理论模型。
technique of carrier modulation in Moiré interferometry is important in displacement measurement of an object.───在物体变形场的测量中,云纹干涉的载频调制技术有重要作用。
