A novel method for reducing greatly the nonlinear errors in heterodyne laser interferometry
外差干涉非線性誤差修正方法研究 -
The scheme is designed based on these researches. for traditional laser rang finders, most of them use heterodyne method as the phase shift measurement. the advantage of heterodyne method is the high measurement accuracy, but its disadvantage is the low measurement velocity
傳統的相位激光測距大部分都採用差頻數字測相，差頻測相的優點在於由於頻率的降低，這樣必然意味著測距精度的提高，但其缺點是測距速率低。
