Default Optical Tachometer - New Idea

Further to my recent post .....

http://forum.xda-developers.com/show...php?p=15399757

I noticed on a 'QR Reader ' app that it seemed to invoke a 'raster effect ' overlayed ? on screen.

This method - an adjustable speed raster overlay - sounds as if it could be feasible to freeze spinning objects.......

What do you guys think ???


Thanks again for your interest and input......
