>Muscle wire would be too slow...mirrors are a possibility, but would We have a project looking to do this with Bragg cells (Rich/Brian, you listening?). A Bragg cell is a solid state crystal that changes its refractive index when you put electicity across it. Used in optical computing. Quartz is a low-end example. So, the idea is shine a laser through the first Bragg cell for X dimension scanning and through the second Bragg cell for Y dimension. Voila', a solid state, no moving parts scanner. About 15 degree FOV we hope. Problems: 1) Getting a bright enough laser 2) If the scanning fails, not blinding someone with it As MTV News says: You heard it here, first.
