The experimental verifications that HOEs made with dichromated gelatin were heated with a laser beam were given. 并給出了激光加熱重鉻酸鹽明膠全息光學(xué)元件的實(shí)驗結果。
The BOE manufacture and laser or electron beam writing are much riper methods.The BOE manufacture has disadvantages of long period,high cost and difficult alignment. 衍射光學(xué)元件有很多制作方法，比較成熟的有二元光學(xué)元件加工方法和激光或電子束直寫(xiě)技術(shù)加工方法。
