显微镜. 光照特性的定义和测量. 第1部分: 使用亮视野显微镜术测定的图像亮度和均匀度

[中文适用范围]： 本部分规定了明场光学显微镜中图像亮度和均匀度测量的方法。这些测量仅在适合电子成像设备检测的图像平面或中间图像平面上定义。 本部分还指定了如何进行图像亮度和均匀度测量，并将其信息提供给用户。 注意：本范围特意限制为电子成像设备及其（中间）图像平面。通过目镜进行视觉观察将需要不同的测量程序，从而导致描述测量程序的不明确性。尽管如此，本部分仍可对使用目镜观察中间图像平面的情况提供有用的估计值（这在本部分范围内）。 [外文原描述]： ISO 19056-1:2015 specifies procedures for the measurement of image brightness and uniformity for bright field light microscopy. These measurements for image brightness and uniformity are defined in image planes or intermediate image planes only, when these planes are suitable for detection by electronic imaging devices. ISO 19056-1:2015 defines how image brightness and uniformity are measured and how this information is provided to the user. NOTE The scope is intentionally limited to electronic imaging devices and (intermediate) image planes. The visual observation by means of eyepieces would require a different measurement procedure and hence result in unambiguities in the description of measurement procedures. Nevertheless, this part of ISO 19056 will give useful estimates for the image brightness with visual observation as in this case, an eyepiece is used to observe an intermediate image plane (which is under the scope of this part of ISO 19056).
