3 using current injecting frequency modulation method and modulating sine wave around the resonator point , the lock - in phenomena is observed in a comparatively short period of time . this has achieved the basic goal for a closed loop r - fog
3 、采用電流注入法，在諧振點(diǎn)附近進(jìn)行正弦調(diào)制，實(shí)現(xiàn)了對(duì)諧振點(diǎn)的短時(shí)間鎖定，達(dá)到了閉環(huán)光纖陀螺設(shè)計(jì)的首要基本要求。
In the end , this thesis tests the resonator with three methods in case that it is both open looped and closed looped , and gets the results listed below : 1 taking 1 mhz frequency width ld as the light source , using current injecting frequency modulation method , the output characteristic of the resonator is got , which proves that the laser used in the lab can be used to modulate the frequency using current injecting frequency modulation
本文最后采用三種不同的方法對(duì)諧振式光纖陀螺進(jìn)行了開(kāi)環(huán)和閉環(huán)的實(shí)驗(yàn)測(cè)試，并取得了以下實(shí)驗(yàn)結(jié)果： 1 、用頻寬1mhz的ld作光源，采用電流注入調(diào)頻的方法，觀測(cè)到了諧振腔的輸出特性曲線。證明了實(shí)驗(yàn)采用的激光器可以通過(guò)注入電流的方法實(shí)現(xiàn)調(diào)頻。
