清晰对比、无雾的 3D 样本实时图像
历史上,宽场显微镜并不适合对大样本/标本体积进行成像。图像背景(BG)主要来源于观察样本的失焦区域,显著降低了成像系统的对比度、有效动态范围和最大可能的信噪比(SNR)。记录的图像显示出典型的雾霭,并且在许多情况下,无法提供进一步分析所需的细节水平。处理厚三维样本的研究人员要么使用替代显微镜方法,要么尝试通过后处理一系列图像来减少雾霭。

一条线索都不能少——没有显微镜,就没有法医学
没有线索,就没有犯罪。线索可能很明显,例如犯罪现场的弹壳或者门锁被撬坏的明显痕迹。然而有的时候,线索可能小到微观世界。除了经典的指纹信息,犯罪者还会留下毛发或纤维痕迹。

图像分析 50 年
现代图像分析系统对来自自动显微镜和数码相机的图像执行高度复杂的图像处理功能。50 年前,第一套图像分析系统是模拟系统,以摄像机为基础,面积测量可通过仪表读取。不过,它标志着这一领域自动化的开端。
