分析比較了數(shù)碼相機和攝像機的特點和優(yōu)勢,利用數(shù)碼相機的長焦距鏡頭、高像素、高靈敏度和彩色成像特性拍攝低照度譜線,獲得了清晰的圖樣。介紹實驗過程參數(shù)設(shè)置和調(diào)整要點、參數(shù)計算方法以及更高性能的同類設(shè)備。解決了背景干擾下的弱光數(shù)字化成像問題,減少了磁場電流變動以及實驗設(shè)備的不確定因素,改進實驗效果和提高實驗質(zhì)量。

This article compared the characters and advantages of digital cameras and cameras. It can take a clear picture of weaken spectrum , by auto colorful digital camera with high sensitivity , high pixels , and long distance focus lens. And the article introduced the parameters setting and key of adjustment in lab processing , parameters calculating methods , and other
higher performance equipments. The digital image of weaken spectrum in the background of the view is solved. The influence of magnetic current changes and the factors of errors are greatly reduced by decreasing the time of exposure. So the experiments are more effective and gotten a good quality.
