How to increase the viewing area of an optical mouse?

Hello, I'm just wondering if any of you guys knew how to make the viewing area of an optical mouse bigger. I have an optical mouse, and of course the viewing point is only as big as the hole for the laser is. I'm wondering if I can make it bigger, so if there was a sheet of paper, with the mouse under it, it would track something moving on the paper. basically like this finger-paper-mouse --- | >

The optical mouse is a single pixel camera - I am not sure what the point of making the viewing are bigger would be. you will not get a picture of the page. In effect lifting the mouse up from the surface will make the field of view bigger - a lens would be necessary to maintain focus - it would be hard to set up and adjust.
