The key components in laser gyro is he - ne ring laser, and the reciprocal action theory between light and medium is the base in studying the ring laser, use the lamb half classical theory, and on the base of density matrix theory, the optical brounch equation was established, which described the movement of amplifying medium atom in the ring syntonic cavity, and according to the medium polarize theory the self consistent equations was deduced, which describe the light intensity and phasic of the counter - propagating wave. on the basis of this equations, adopted the simulation software matlab and virtual instrument programming language labwindows / cvi, we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium, mode pushing effection, burned hole effection and pattern competition, lock - in of frequency and the characteristic of light intensity and phasic of the counter - propagating wave in laser gyro
激光陀螺的核心部件為he - ne環形激光器，而掌握光與介質的相互作用理論是研究激光器的關鍵，採用拉姆半經典理論為主，在密度矩陣理論的基礎上，推導環形諧振腔中描述he - ne氣體增益介質原子運動的光學布洛赫方程，運用介質極化理論得出描述激光陀螺反向行波的光強、位相所滿足的自洽場方程組，在此基礎上，運用matlab模擬軟體和虛擬儀器編程語言labwindows / cvi ，對激光陀螺中的介質增益色散特性、頻率牽引效應、燒孔效應及模競爭、閉鎖效應及環激光的光強和相位特性進行模擬試驗研究，並且運用全量子理論，對激光工作原理進行分析，得出二能級系統單模輻射場的光子數密度分佈，得出激光場的光子統計分佈，模擬激光場的動態建立過程。It can be used in any complex environment, can locate all paths from transmitter to receiver which avoid redundant calculation, and it is a standard 3 - d forecast model ; in addition, it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently, the proagmme can back - search the virtual fountain tree when it is running. these operation increase the calculate speed and it result in the higher receive efficiency and precision. the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models. the comparsion result indicate the new model is a better model
它可應用於任何復雜的傳播環境中，能找到發射機到接收機之間的所有電波傳播路徑而無須冗餘的計算，是一種準三維的預測模型；另外，從本質上講，它仍然是一種基於鏡像理論的點對點的射線跟蹤法，所以它無須進行接收測試；而且由於採用了反向演算法，運用數據結構中多叉樹的概念，先確定需要計算的場點位置，找出所有能從源點到達場點的射線，並且可一次性建立一個虛擬源樹，以後每次的計算只要通過對該樹進行後序遍歷即可，大大提高了運算速度，因而有較高的接收效率與精度。本文對該模型進行了相應的模擬，並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射線跟蹤確定性模型的預測結果進行了比較，結果表明了該模型的優越性。
