Description / Abstract:
This part of ISO 19056 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.
This part of ISO 19056 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).
