Output power equalization of laser dual spectrum lines is a special requirement which is put on its laser source by two wavelength beat - wave absolute distance interferometry
摘要雙譜線功率一致性是拍波干涉測長方案對激光光源提出的特殊要求。 -
On the basis of analyzing the output signal of a two wavelength beat - wave absolute distance interferometer, this paper proceeds from the realities of the aiming method of the beat - wave interferometer, conducts an analytical investigations on the dependence of the aiming accuracy of the beat - wave interferometer on laser dual - line output power equilibrium, propose two new concepts - a basic aim blind area and a blind area expansion, and establishes an analytical expression between the blind area expansion and the relative power difference of laser dual lines
本文從拍波干涉儀對準方法的實際出發，在分析雙譜線拍波干涉儀輸出信號的基礎上，研究了雙譜線功率不一致與拍波干涉儀對準精度的關系，提出了基本對準盲區和盲區擴大量的新概念，建立了描述盲區擴大量與雙譜線相對功率差之間關系的解析表達式。
