object distance meaning in English
目标距离
物距
Examples
- The object distance for the left face of the cube is 63cm .
立方框左侧面的物距为63cm。 - The object distance for the left face of the cube is 63cm
立方框左侧面的物距为63cm 。 - The appearance position of hot - image satisfied the rule of z2 = z1 - lv , z2 is mean the image distance , z1 is mean the object distance , and lv is mean the distance between the nonlinear medium . the theory is also validated by the optical propagation software . if n = 1 , then the nonlinear medium is only one , lv = 0 , and it will satisfy the rule z2 = z1
四、从非线性近轴波动方程基础上用散射矩阵理论推导了级联介质的热像规律,得出级联介质的热像位置满足z2 = z1 - lv ,其中z2为像距, z1为物距, lv为级联介质间的距离,并用光传输软件得到了验证;发现级联的非线性介质可以看成单一的非线性介质相连,散射点对级联介质的每一段非线性介质成像;当只有一段非线性介质时,可以认为lv为零,满足z2 = z1 。
