Claim:
1. An optical metrology and image correction device comprising: a point size light source adapted to emit a beam of light; and a translucent mask configured and disposed to receive the beam of light emitted from the point size light source, the translucent mask rotatably disposed to rotate from a first position wherein the beam of light is received by the translucent mask in a direction orthogonal to the translucent mask to a second position wherein the beam of light is received by the translucent mask at an angle offset with respect to the translucent mask, wherein when the beam of light is received by the translucent mask in the first position, the beam of light creates an undistorted image on a surface of a target object positioned distally from the point size light source and distally from the translucent mask, and wherein the translucent mask and the surface of the target object are parallel to one another to define a first mask and target object position.
