METHOD FOR NON-CONTACT MEASUREMENT OF RELATIVE DISPLACEMENT OR RELATIVE POSITIONING OF A FIRST OBJECT IN RELATION TO A SECOND OBJECT INDUCINGLY.

摘要

The invention relates to a non-contact measurement method of relative displacement or relative positioning of a first object with respect to a second object such as segmented mirrors of a giant telescope, in which: at least one transmitting coil, placed on the first object, by an alternating excitation signal, - at least one ac voltage generated by mutual inductance is detected in at least one receiver coil placed on said second object, said at least one coil receiver being placed in a magnetic field created by said at least one transmitting coil, and determining the relative displacement of the first object with respect to the second object from said at least one voltage generated on said at least one receiver coil.
