It will introduce in a systematic way to the fundamentals of crystal optics, the basic component of polarization microscope and some basic concepts, such as indicatrix, optical orientation, extinction, compensation, interference color, compensation principle and so on
本課程將系統地介紹晶體光學的基本原理、偏光顯微鏡的基本組成和光率體、光性方位、消光、干涉、消色、補色法則等基本概念。The thickness had some influence on the development of the banded spherulites : when the thickness reduced to some degree, pcl would develop chrysanthemum - like spherulites, which had no extinction rings or the maltese cross pattern under the crossed polarized optical microscopy. the results of the phase - contrast microscopy showed that growth speed of the chrysanthemum - like spherulites along the radius was not constant
發現薄膜厚度對球晶的生長有一定的影響,當共混物膜薄到一定程度時, pcl不能形成環帶球晶,而是形成一種類似菊花狀的晶體,在偏光顯微鏡下看不到環帶,也沒有典型球晶所特有的maltese十字消光圖案。Special features for copying inputting originals auto paper select, auto scaling select, vertical horizontal independent anemographic magnification, final scale adjustment, copy density adjustment 7 degrees, scan start position adjustment, and copy position adjustment, top bottom bottom margin setting, mirror image, trimming, negative positive inversion, header, reference input, rotate image, sharpness, contrast, additional copy, scanning speed change

激光偏光棱鏡,以其優良的消光比性能和高抗光損傷閾值性能,倍受科技工作者歡迎。This paper designs an optical system based on above to measure the small angle of the laser beam. a non - polarized beam splitter ( npbs ) is used to split the incident beam into two branches, and a rhombic prism agglutinated by two right - angle prisms is placed to realize total internal reflection twice in each branch. it not only improves the measurement sensitivity and linearity, but also increases antinoise ability by the differential optics
本文正是基於這一原理設計了測量光束微小偏轉角的光路系統,用消偏振分光棱鏡將入射光分為兩路,並在兩路分別用兩個直角棱鏡組成的斜方棱鏡來實現兩次全內反射,不但提高了測量靈敏度和線性,還利用差分光路的特點提高了抗干擾能力。In this thesis we analyze in detail the influence, created by random change of the optical wave polarization, on the output of the interferometer. then several principles of eliminating polarization - induced fading are introduced, and the principle that inserting two faraday rotator mirrors into the end of michelson fiber interferometer to eliminate the fading is analyzed in detail. this method can eliminate polarization - induced fading without additional signal processing, and make the output of the sensor stable
其中,本文詳細分析了光波偏振態的隨機漂移對干涉儀輸出的影響,介紹了目前幾種消偏振衰落技術的原理,著重討論了在光纖michelson干涉儀末端加兩個法拉第旋轉鏡的消偏振衰落的原理,該方法不需要任何附加的信號處理就可以消除偏振衰落,使干涉儀輸出穩定。According to the principle of correlation detection, an automatic measurement system for extinction ratio of polarizer consisted of monochromator and dsp lock - in amplifier and compurer is designed not only to eliminate the influence on measurement accuracy caused by drift of intensity of light source but also to obatain approximate extinction spectrum
摘要基於相干檢測原理設計了一套由單色儀、數字鎖相放大器和計算機聯合使用的透射式偏光鏡消光比智能化測試實驗系統,採用雙頻雙光路分光單探測器接收鎖相放大器分離信號比對法進行源補償測量,克服了光源光強漂移所帶來的影響;實現了可見光區消光比的精確自動測量,而且可以測得近似的消光光譜。分享友人
