Image quality measurements
There are many ways to evaluate image quality, including
MTF, 3-bar contrast, and visual examination of the PSF,
just to name a few. These measurements are common to
many different OpticStudio setups, so they are discussed
in a separate chapter on measuring image quality.
Measuring EFL, BFL
These measurement are not applicable to an afocal module.
At the risk of stating the obvious,
if the module can be disassembled it is possible to
measure the EFL of the components separately.
Finding the Exit Pupil
This measurement is not supported by the standard OpticStudio.
However, it is possible to visualize and plot pupil location
vs field angle with the optional pivot mount.
Measuring Magnification
"Magnification" is the ratio of image height
to object height. The EFL wizard in PixelScope makes
it easy to do this with a few clicks of the mouse. For
more information see measuring
magnification.
