"Edge Detection" also can be an image processing thing.

WOW.  Now that description was updated, my post was WAY off,
but sure seemed correct with the earlier description.

Hopefully someone else has help for what you really need.

We need a LOT more information on what you're doing -> application or constraints, lighting, motion, speed. accuracy, edge length, proximity, artifacts, ambient noise, etc etc etc etc

Listing an optical detector p/n is about the same as saying you are using a 5k resistor.

1st rule of design: frame the problem with proper and adequate constraints.
