Question copied from article
Someone wrote a question into the article, i removed it there and copied it here -- 84.190.192.91 17:30, 23 January 2007 (UTC)
- This page looks like it has been lifted from a larger article. For example, the following sentence appears "The OTF accounts for aberration, which the limiting frequency expression above does not." but there is no previous refrence to a "limiting frequency expression". Please explain what this is.
The MTF definition presented appears to be inconsistent with standard usage. For situations where the object space input phase varies randomly from point to point (i.e., non-coherent imaging), the MTF is the normalized Fourier tranformation of the convolution of the point spread function with itself.
