qCMOS 相机与 EM-CCD 相机 vol.1 – 光子计数相机的性能比较
本文将指导您为您的用途选择合适的光子计数相机。
用途
中性原子，离子阱
中性原子和离子在阵列中逐个排列，用作量子计算的量子位。量子位状态可以通过观察它们各自散发的荧光来确定。鉴于荧光测量需要在短时间内完成，故还需要具有极低噪声和很高速度的光电检测器。ORCA-Quest 2 既可以对整个量子位阵列进行诊断，也可以对每个量子位进行状态检测，具有极低的噪声特性和快速读出能力。此外，QE 覆盖主要离子和原子物质的广泛波长范围。

量子光学
量子光学使用单光子源来利用单光子的量子特性。鉴于光子数分辨探测器在量子光学调查研究中的用途，对光子数分辨探测器的需求日益增长，以准确区分进入探测器的光子数。光子计数相机是相机技术领域的一个新概念，有望在该领域取得全新发现。

案例研究
超分辨率显微镜
超分辨率显微镜是指一系列获取空间分辨率高于衍射界限的显微镜图像的方法。超分辨率显微镜需要具有极低噪声和小像素尺寸的科学相机，从而实现更高的分辨率。

生物发光
生物发光显微镜因其相对于传统荧光显微镜的独特优势（如无需激发光）而备受关注。生物发光的主要缺点是光强度极低，导致曝光时间长且图像质量低。生物发光调查研究需要高灵敏度相机，甚至长时间曝光也是如此。

植物中的延迟荧光
植物会释放很小一部分光能量，在一段时间内作为光进行光合作用。这种现象被称为延迟荧光。通过检测这种微弱光，可以观察化学物质、病原体、环境和其他应激源对植物的影响。

案例研究
幸运成像
当从地面观察星星时，由于大气湍流，星星的图像可能模糊，因此大大降低捕获清晰图像的能力。但是，由于曝光时间短且大气条件适宜，有时可以拍摄到清晰的图像。因此，幸运成像是一种获取大量图像并在对齐时仅整合最清晰的图像的方法。

成像设置
自适应光学
通过自适应光学方法，系统可立即校正受大气波动干扰的入射光的波前。为了执行实时和高精度的波前校正，相机必需以高速和高空间分辨率获取图像。此外，由于波前校正是在测量激光导星的极暗状态下执行的，因此相机还需要具备高灵敏度。
