A system for scanning a target is provided. A light source directs a beam of light toward a radially-arced piezoelectric material having a reflective surface. The reflective surface directs at least a portion of the beam of light to the target. A power source provides movement in the radially-arced piezoelectric material to scan at least a portion of the beam of light across at least a portion of the target. The at least a portion of the beam of light is reflected onto a photosensor to provide an electrical signal representing the reflected light.
