光柵衍射（Diffraction Gratings）的研究

本文共17頁 5954字
摘要
光柵是一種折射率周期性變化的光學元件。最常用的光柵是由大量等寬、等間距的平行狹縫組成的，通常是在一塊平面玻璃上用金剛石刻制、復制或用全息照相等方法制成。
光柵是一種重要的分光元件。光柵不僅適用于可見光波，還能用于紅外和紫外光波，常被用來精確地測定光波長及進行光譜分析。以衍射光柵為色散元件組成的攝譜儀和單色儀是物質光譜分析的基本儀器之一。光柵衍射原理也是晶體X射線結構分析和近代頻譜分析與光學信息處理的基礎。

Abstract
The monochromatic light goes through the list and stitches the diffraction streak that afterwards may to take shape light and shapely alternate with ,Moreover may be through the streak breadth calculation light wave wavelength .Yet the use is alone stitched and is accurately surveyed is fully difficult ,For when stitches broad A is more great ,Streak clearance very narrowly is difficult to distinguish ；But stitches broad A hour ,Light powerful very much feeble ,Also not benefit the measurement ,The parallel in the way of much and so on intermission replace the broader list to stitch taking shape the raster in case carefully stitching ,Utilizes the raster may be exact the measurement light composes ,The physics being living heaves the fully significant sense in the test .
The appearance of the diffraction queen of the ray of this test by means of watch after the raster ,Comprehend the raster diffraction distinguishing feature ,Study to survey raster constant D ,Along with Gong's light either the atrium light feature composes string wavelength .
