Abstract
A method and system are provided for inspecting a surface of an object with an optical scanner and a laser vibrometer. The method includes the steps of: (a) mapping at least a portion of the object surface using the optical scanner; (b) projecting a beam of light from the laser vibrometer onto the object surface at a measurement point; (c) locating the measurement point relative to the object surface using the optical scanner; and (d) measuring a position of the object surface using the laser vibrometer to determine, for example, a deflection of the object surface.

A method for inspecting a surface of an object with an optical scanner and a laser vibrometer, the method comprising:
- mapping at least a portion of the object surface using the optical scanner;
- projecting a beam of light from the laser vibrometer onto the object surface at a measurement point;
- locating the measurement point relative to the object surface using the optical scanner;
- and
- measuring a position of the object surface using the laser vibrometer.
A system for inspecting a surface of an object, comprising:
- a laser vibrometer adapted to project a beam of light onto the object surface at a measurement point, and to measure a position of the object surface;
- an optical scanner adapted to map at least a portion of the object surface, and to locate the measurement point relative to the object surface;
- and
- a controller adapted to correlate the measured position of the object surface to the location of the measurement point.
