ABSTRACT:
A subject having a test surface is held by a holder so that an axis line of the test surface intersects the direction of gravity and applied with a load, from above and beneath, that is optimized for accurate measurement of surface profile of the test surface. For optimization of the load, the test surface is applied with variable exploratory load strong enough to cause bending deformation in the test surface and a linear-functional relationship existing between more than two different exploratory loads and sizes of surface deformation caused with the different exploratory loads is derived. With the aid of linear-functional relationship, a load that induces the subject to cause surface deformation less than a predetermined size of surface deformation admissible, for example, as a manufacturing en-or is used as an optimized load.
