Commercial Optical Targeting System for XY Table

[bjb123]

I'm looking for some direction on finding an off the shelf targeting system for an XY system. The XY system motion is approx. 2' x 2', and it needs to locate various positions within that envelope. Instead of paying for a high priced precise XY system, we want to utlize a simple XY system and a positioning feedback method to zero in on the target location(s) +/- .020". We would like to know of any sources for such a targeting system (optical, magnetic, acoustic, etc). It needs to be fairly small, ie. 3"x3"x3" or less. Any advise on vendors, contacts, or personal experience with designing such a targeting system would be greatly appreciated. I've started searching the web, but most everything is military based. We are looking for less precision, less cost, and smaller application.
