ABSTRACT:
An instrument for determining the profile of a surface. Two hinge plates are attached to each other at a hinge joint. A collimated light source on one of the hinge plates produces a spot on a position sensitive photo detector on the other hinge plate. An electrical circuit is provided to produce an electrical signal based on the relative position of the spot as the instrument flexes as it is slid along the surface. In preferred embodiments the electrical signal is a measure of the surface profile or the change in slope of the profile.
