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.
