Abstract:
A system that guides at least one beam of light through axes of a mechanical positioning system and directs the at least one beam of light at an object under test, comprising:at least one remote light source that generates the at least one beam of light; a mechanical armature operable to receive the at least one beam of light from said at least one remote light source and transmit said at least one beam of light along axes of motion of said mechanical armature via an optical transmission channel, and wherein said mechanical armature operates to deliver the at least one beam of light to any location within a workspace; a positioning controller operable to direct that said mechanical armature be positioned according to an optical scan plan; an alignment fixture within said optical transmission channel coupled to a position feedback sensor used to determine if the at least one beam of light is obstructed within said mechanical armature; a first optical assemble that directs the at least one beam of light to the object under test, wherein at least one beam of light generates ultrasonic displacements in said object under test; an optical receiver operable to collect light incident from the at least one beam of light on said object under test and modulated by said ultrasonic displacements in said object under test; and a processor operable to determine from said collected light and display an internal structure of said object under test.
