数码显微镜摄像头和图像分析的基础技术术语定义

现今绝大多数显微镜都配置了摄像头。摄像头的特征通常决定了所采集到的图像是否能够揭示出研究人员希望观察到的现象。但深入到摄像头术语时，技术术语十分繁杂。我们汇总整理了最为重要的术语及其简明释意以便提供方向。这些术语按字母顺序排列。

The rectangles represent the field of view (FOV) of a Leica digital camera when installed with various C-mounts (red 0.32x, blue 0.5x, green 0.63x).

30000:1放大率到底意味着什么？

关于光学显微镜性能的一个重要标准是放大率。本报告将为数字显微镜用户提供有用的指南，以确定放大率值的有用范围。

临床显微镜：相机选择的考虑因素

过去几年，病理学实验室对图像的需求显著增加，无论是在组织病理学、细胞学、血液学、临床微生物学还是其他应用领域。除了诊断记录外，图像还服务于许多其他目的。然而，通过目镜观察到的图像和数字图像在本质上是不同的，一个是光学图像，另一个是数字图像。从与相机相关的几个方面来审视这一过程，将有助于确保您能够获取所有细节和颜色保真度的图像。
