I've been reading your other posts and looked into the Sharp GP2D02...
http://www.junun.org/MarkIII/Info.jsp?item=30# ...It has it's own emitter built in but I think beter accuracy could be obtained by taking the unit apart and increasing the distance between the emitter and the sensor...
Anyways, are you using a laser rangefinder for the system you're building? Very curious.
