conjugate direction 中文意思是什麼
conjugate direction
解釋
共軛方向-
It has been deduced that the search direction remains the same but that the step length decreases in optimizing the improved cost function with the conjugate gradient algorithm from the gradient of the cost function that the fir filter apporaches the contrary point spread function ( psf ) more, and that the estimated image is closer to the original one
從代價函數的梯度入手推導出共軛梯度演算法，其搜索方向保持不變而搜索步長變小，使濾波系數更加退近於點擴展函數逆運算元，從而使估計圖像與原始圖像更加接近。 -
In photorefractive crystal light illumination changes the refractive index of the crystal due to linear electrooptical effect, which in turn changes the light distribution. as a result of the development of this process, a beam, called the phase conjugation wave, leaves the crystal back along the direction of the incident beam and is its phase conjugate replica
光折變晶體在光輻照下，通過晶體中的線性電光效應而產生折射率隨光強的空間分佈而變化，即在晶體內建立起體相位柵。 -
We draw the conclusion that 1000ppm cr : sbn crystal has greater phase - conjugate reflectivity than 500ppm cr : sbn crystal. we find that the phase - conjugate reflectivity depends on the direction of two - wave coupling. we utilize 1000ppm cr : sbn crystal to correct a distorted picture because of its super phase - conjugate characteristic
還討論了光束耦合方向對cr ： sbn晶體的四波混頻相位共軛特性的影響；利用cr ： sbn晶體四波混頻相位共軛特性進行了圖像畸變消除的實驗。
