HiCAM 像增強型高速相機
HiCAM是一款針對弱光條件下的高速成像相機。其擁有1.3M芯片，可以在全畫幅情況下最快幀率達到500fps捕捉清晰圖像。如果減少采集畫幅可以獲得更高幀率。
關鍵性能：
- 高分辨像增強器：高分辨二代或三代像增強器，響應范圍可從紫外、可見到近紅波段。
- 超短門控：最低可到40ns（FWHM），且電子抖動極小
- 門控可高重復頻率工作：最高可達100KHz
- 緊湊型設計
HiCAM 像增強型高速相機應用：
- 燃燒實驗
- 等離子體物理
- 時間分辨熒光
- 顯微動力學實驗
- 激光誘導熒光（LIF）
- 粒子成像測速（PIV）
- 血流分析
- 微流控芯片技術
