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)[reply]

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.

Doh!

I'm sorry, but I regard myself as a reasonably intelligent person and have been told by many people that I am regarded by them as highly intelligent. So what the blazes is going on here? I turned to this link from the "Spy Satellites" article and instead of an explanation found a highly technical article which requires a great deal of prior knowledge on the subject at hand. As you may assume, I don.'t have that knowledgebase and therefore found the article less than useful. Indeed, I walked away less clear and decidedly more frustrated.

Please don't think I am being insulting to the author/s in any way, I am merely conveying my personal experience as best as I can. In my own experience I know it can be far too easy to be too close to one's work and not realise one is unintentionally leaving folks behind. And as an encyclopedia is an 'everyman' sort of reference, I feel this article needs further work, perhaps with a clear mind to it being a Wikipedia article and not a technical reference work of the field thus making it possible for the lay person to understand.

Thanks and kindest regards,

I agree this is an overly technical article with no non-technical introduction. I didn't see it linked from spy satellite. This page needs love, but it is intrinsically technical as opposed to say image resolution; the page that linked you here should probably link there or somewhere similarly less-technical. —Ben FrantzDale (talk) 12:38, 23 November 2010 (UTC)[reply]

I regard myself as an expert in this area, having worked on the development of ccd cameras and image conversion for many years. So I have re-written from scratch. Hope this meets with approval. -Lindosland (talk) 11:20, 25 April 2011 (UTC)[reply]

It's still quite technical. It could probably be improved with a visual example or two. 216.118.216.42 (talk) 19:35, 6 July 2011 (UTC)[reply]

Mystery term in equation

One of the equations in the "advanced" section introduces a mystery term λ(ξ,η) -- this needs defining elsewhere, or the equation is simply baffling, rather than informative. -- The Anome (talk) 21:37, 4 February 2012 (UTC)[reply]
