 Joan, 1. It looks like a 3-d problem to me. 2. Can you measure the distances sensor-to-sensor? 3. Do you get shortest distance sensor to target or distance "at this angle" ( which I don't know that well ) 4. Can you move the target in a known pattern? 5. Remember that you need one more equations than unknowns. I think this works with 4 sensors, being able to get sensor to sensor distances, being able to read shortest distance sensor to target, and a sphere. On second thought, IF you can trust being in plane, then for each sensor, you have 2 distances. Knowing the 2 diameters, you have the distance to center, and the angle of incidence. IF you know the distance between sensors, you can get relative position for target axis and sensor "array". Then you could check x-y motion for accuracy and squareness. Of course you don't know "where you are" wrt to anything else, or at what angles. dave
