What you are making in itself is an analog to digital converter. Questions that pop off the top of my head:
1. different angles will have different lengths to the detectors, are you thinking of making the detectors curve to the geometric shape? 2. Since the laser will not be a point but a spreading of light, how will that affect the spreading at different angles on a curves surface, will you hit too many bits at once? 3. The mass of the object and its center point holding method will probably provide some distortion due to momentum change and spring like affects. 4. As I can see it, each optical detector is a level indicator. To get the same resolution as a 16-bit A/D you would need 65000 detectors, is that feasible?
