We received a request a while back to add some pretty weighty terms to our online glossary: MTF and OTF. Aka: modulation transfer function and optical transfer function.
After a lot of work trying to condense these definitions down into the most distilled, layman-friendly versions possible, we decided these guys needed their own articles, too!
For the quick glossary definition, you can find them alphabetically at:
For a longer, detailed explanation with pictures and a graph and everything (!) see this link:
The full article is still geared at someone with a beginner's understanding, not to worry. We worked hard at giving a thorough, but still easy-to-comprehend lesson with as little jargon as possible.
If anything is still unclear, or if you have comments or questions, please let us know! Or if there's anything else you'd like defined for laymen, hit us up. These articles and the glossary are open for continual improvement. You help make them better!
