I have a question about the following two sentences:
"The image is distorted and its length is reduced more than its height.
The magnification transverse to the axis is greater than the longitudinal magnification along the axial direction."
because I am translating this and have absolutely no idea what they are referring to. When I tried to test this, I took the lengths and heights in the image and original and compared them. In the instance I was measuring, the ratio of the lengths (parallel to the optical axis) was 4 times larger in the image than the original, whereas the heights were 1.25 and 2.9 times larger in the image than the original.
So, again, I am confused, or maybe I am misunderstanding the sentences: How is it that the length is enlarged less (or reduced more, that also confused me) than its height when distorted?
