ABSTRACT:
The invention is a non contact laser inspection self centering device to inspect the counter sink portion of a counter sunk fastener hole on a surface. In detail, the self centering and seating device includes a combination laser transmitter and receiver for transmitting a laser bean across a surface and for receiving the return signal from the surface. A self centering device is attached to the combination laser transmitter and receiver for aligning the laser transmitter with the fastener hole such that the transmitted and received laser beam passes across the center of the counter sink portion of the fastener hole. A computer system is connected to the combination laser transmitter and receiver for analyzing the transmitted and returned laser signal from the surface and determining if the counter sink portion of the hole is within tolerance.
