HiCAM 像增强型高速相机
HiCAM是一款针对弱光条件下的高速成像相机。其拥有1.3M芯片，可以在全画幅情况下最快帧率达到500fps捕捉清晰图像。如果减少采集画幅可以获得更高帧率。
关键性能：
- 高分辨像增强器：高分辨二代或三代像增强器，响应范围可从紫外、可见到近红波段。
- 超短门控：最低可到40ns（FWHM），且电子抖动极小
- 门控可高重复频率工作：最高可达100KHz
- 紧凑型设计
HiCAM 像增强型高速相机应用：
- 燃烧实验
- 等离子体物理
- 时间分辨荧光
- 显微动力学实验
- 激光诱导荧光（LIF）
- 粒子成像测速（PIV）
- 血流分析
- 微流控芯片技术
