3. OverDrive Plus (ODP)
OverDrive Plus (ODP)是一種全新技術(shù),從 Boulder 非線性系統(tǒng)(BNS)專門為Meadowlark 光學(xué)反射空間光調(diào)制器(SLMs)設(shè)計。當使用我們的 SLMs ODP時,連續(xù)全息圖之間的相變時間將大大減少。使用ODP顯示降低2 - 8 x 標準的光學(xué)響應(yīng)時間。這個響應(yīng)時間減少歸功于三個獨立的技術(shù)開發(fā)集成在一起的組合產(chǎn)品: Transient Nematic Effects, Phase Wrapping and Regional Look‐up‐ ables。
主要特點:
·更快的響應(yīng)時間通過瞬態(tài)向列的影響,相位纏繞,區(qū)域校準。
·通過軟件啟用/禁用ODP的能力。
·利用GPU通過OpenCL減少計算的時間中間全息圖。
·提前計算中間全息圖幀速率更快的能力。
·區(qū)域標定程序256 x 256和512 x 512像素SLMs使像素水平LUTS和校準數(shù)據(jù)。
