light path length 中文意思是什麼
light path length
解釋
光程長-
The theoretical analysis shows that mz - ifog can be used to detect the rotation rate of moving objects. a systematic analysis of transfer characteristics of mz - ifog is made. performance - limiting factors, including the path - length difference, the disturbance of temperature fluctuation and stress from working environment, the quality of light source, are all discussed along with methods to reduce their effect on the output signal
本文用系統的方法分析了mz型干涉式光纖陀螺儀的光傳輸特徵，指出了其較大的非互易性因素-臂長差的存在，分析了工作環境因素（溫度，應力） 、光源質量（輸出光束中心波長、光功率波動及偏振態波動）對系統工作性能的影響，並指出了減少系統非互易因素、抑制噪聲、提高檢測穩定性的措施。 -
A distant field interference of non - single - core light beams is analysed in a transparent liquid or solid when the bubble is irradiated with laser, a formula on optical path length difference is derived, interference regions and causes of interference rings thick inside and thin outside are analysed, the diameter of bubble can be measured by method of interference, the size of bubble and refraction index of gas inside the bubble can be measured in the depths of medium
摘要對透明液體、固體中氣泡在激光照射下產生的一種非單心光束干涉進行了遠場分析，得到了程差公式，分析了干涉的區域、圓環狀干涉條紋內密外疏的原因，通過干涉的方法可以測量氣泡的直徑，能夠用於介質深處氣泡尺寸及泡內氣體折射率的測量。 -
As a new velocity sensor, fvisar has the merit of compact structure, short coherence length, easy to adjustment light path, any fringe constant and so on. the principle of fvisar analyzed from two different theories ( traditional coherent theory and doppler frequency shift theory ) lead to the same velocity equation which is the solid theory foundation of the fvisar design
第二章分別從經典的光干涉理論和多普勒效應兩方面對fvisar的工作原理作了詳盡的理論分析，兩者得出了相同的速度計算公式，從而為全光纖速度傳感器的設計打下堅實的理論基礎。 -
