一、计数脉冲有理化 在标准大气条件下(P_0=760托,T=20℃,f=10托),He-Ne激光波长λ_2=λ_0/w_g,其中λ_0是真空中的激光波长,n_g是空气折射率。当采用基本型干涉系统和电器四倍频时,它的脉冲当量q=λ_g/g。取实用显示单位ε=0.08微米,这样ε和q有差值就造成计算误差。为了保证一定的计算精度,必须按一定规律扣补脉冲,称为计数脉冲有理化。 二,迭代系数的确定法 计数脉冲有理化的方法,就是将每个电脉冲讯
First, the counting pulse physics In the standard atmospheric conditions (P_0 = 760 Torr, T = 20 ℃, f = 10 Torr), He-Ne laser wavelength λ_2 = λ_0 / w_g, where λ_0 is the laser wavelength in vacuum, n_g is Refractive index of air. When using basic interference system and electrical quadruple frequency, its pulse equivalent q = λ_g / g. Take the practical display unit ε = 0.08 microns, so that there is a difference between ε and q, resulting in calculation error. In order to ensure a certain degree of accuracy, a certain regularity must be used to supplement the pulse, which is called count pulse physics. Second, the determination of iterative coefficient method counting pulse rationalization method, that is, each electrical pulse information
