長波通濾光片是wdm的重要組成部分,它的性能直接影響wdm的質量。But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data
但是標準mc演算法存在較大的問題:標準mc演算法實質上是通過閾值分割來提取等值面,閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;標準mc演算法是逐個移動立方體來進行處理,就是說對所有的立方體都要進行一次檢測,演算法執行中30 % ~ 70 %的時間用在對空單元的檢測上,因此需要有一種合理的數據結構對空間數據進行有效的遍歷,以加速對空單元的檢測和過濾;標準mc演算法產生了大量的三角面片,一般重建的組織或器官包含數十萬甚至上百萬的三角面片,難以實現實時的繪制和交互操作;標準mc演算法得到的表面網格並不光滑,會有一些不期望的凹凸,特別是在原始數據有較大誤差的情況下尤其突出。A quantitative analysis for different kinds of gas in the different fields can be carried out through changing the functional modules of filter components
通過更換濾光片組件功能模組,可實現不同測量領域不同種類氣體的定量分析。In this paper they study a position - detecting system based on microprocessor and psd ( position sensitive detector ). the method is as follows : when the ac - signal from psd which is illuminated by modulated light source passes through an active band - pass analog filter, it filters the ac signal which represents the object light source. then the dc - converter circuit transforms it into dc - signal which is used to calculate the position
這一系統採用的方法是通過對位置敏感探測器psd受到調制目標光源照射后輸出的模擬交流信號進行有源帶通濾波,提取出代表目標光源的調制頻率成份,再將該信號轉變為用來參與位置解算的直流信號,然後選用單片機組成硬體電路,對直流信號進行採集處理並與計算機建立通信,把數據送入計算機進行位置解算,分析判別目標光源和psd器件的相對位置。In order to approach above target, we applied a vuv filter on the pre - filter wheel with high transmission in solar ha line. the solar vuv radiation reaches detectors through the filter. then the solar ha images are obtained by each telescope
