>>Only problem would be working out the math of the reading The math would be the easy part. It would be the cotangent(distance laser moves on target /distance from the laser to target) You might want to set it up so that the laser only pivoted. I.e., you would want the laser stationary with respect to its longitudinal position on the string so that the distance from the laser to the target remained the same. Centered over the bridge might be a good place. If you physically moved the laser down the string for each section, you would also have to remeasure your distance to the target for each calculated angle. Of course, if the distance to the target is substantial enough, the variance in distance to target might become insignificant.
