METHOD OF MEASURING THREE-DIMENSIONAL COORDINATES Russian patent published in 1994 - IPC

FIELD: automatics; computer technology. SUBSTANCE: variable electromagnetic field is excited in two points of operation space, which belong to one of coordinate axes of the space. Strength of the field is indicated in chosen point by means of two magnetometric detectors, disposed in align in coordinate remover. Excited field is rotated in any point alternatively in two inverse perpendicular planes and angles of rotation are fixed, at which signal differential, induced in magnetometric detectors, is equal to zero. Coordinates of point of remover are determined with the precision, being higher, than coordinate measurement, performed by means of prototype. EFFECT: improved precision of reading-out. 4 dwg
