方向专题 | 超越器件物理限制，重塑光电感知能力：计算光电智能探测感知方向突破感官边界，看得更远、看得更清，一直是人类认识世界、拓展活动空间的不懈追求。从仰望星空、远洋航行，到地理勘测、对地遥感与目标探测，许多重要的科学发现与工程实践，都始于一次对远方更加清晰、更加全面的观察。四百多年前，伽利略将望远镜用于天文观测，光学仪器由此开始突破人眼的距离限制。此后，伴随光电探测器、数字成像与信息处理...

方向专题｜突破衍射极限，洞见生命深处：计算光学赋能先进生物医学成像

探索微观世界的奥秘是人类长久以来前赴后继的永恒追求。从分子相互作用到细胞动态变化，从组织结构到复杂生命过程，许多重要的生物医学问题，都始于一次更清晰、更快速、更准确的“看见”。早在四百多年前，人类就已经通过光学手段观察肉眼所不能分辨的微小物体。1662年，英国物理学家罗伯特·胡克通过自制显微镜在人类历史上第一次成功观测到细胞，并使用“Cellua”（“细胞”英文单词“Cell”的由来）命名。...

方向专题 | 不用染色也能看清细胞：计算光学三维显微成像

细胞是生命活动的基本单位，但大多数活细胞近乎无色透明。光穿过细胞时，其强度变化十分微弱，许多内部结构仿佛“隐身”了一般。为了让细胞显形，通常需要借助荧光标记、化学染色等外源标记手段。然而，外源标记可能扰动细胞原有的生理状态，持续照明还会引发光漂白和光毒性，因此难以满足活细胞长时间、连续观测的需求。除了让透明细胞“看得见”，现代显微成像还需要进一步回答细胞内部“发生了什么、变化了多少”。因此，...

方向专题｜从二维图像到三维世界：计算光学三维成像计量

人类感知的外界信息，有80%以上来自视觉，而人眼能力受限于视觉性能，在时间、空间、灵敏度、分辨力等方面均存在局限。普通相机擅长记录颜色和明暗，却不一定知道物体离它有多远、表面哪里凸起、哪里凹陷。计算光学三维成像计量，就是借助主动光、相机和算法，恢复物体每个位置的深度与形貌，让机器从“看见”进一步走向“量准”和“理解”。三维成像技术使机器感知三维世界，是智能制造的数据源头目前全球高端视觉传感器...
