A system for scanning a target is provided. A light source directs a beam
of light toward piezoelectric material having an arcuate reflective
surface. The reflective surface directs at least a portion of the beam of
light to a beam expander, which in turn directs light onto the target. A
power source provides movement in the 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. A mirror is further provided between the reflector and the target
to allow scanning of a target at an angle to the system components.
