INTERFERENCE METHOD FOR DEFINITION OF THE POSITION OF THE ASPHERIC SURFACE AXIS AND THE DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01M11/02 G01B11/27 G02B27/62 G01B9/02 

FIELD: optics.

SUBSTANCE: invention can be used in the assembly and alignment of mirror and reflex lenses. Method includes forming of spherical reference and object wave fronts from a coherent source, obtaining an interference pattern as a result of the interaction of the reference and object wave fronts reflected from the reference and aspherical surfaces and determining the position of the axis of the aspherical surface on it. In addition, form a measuring base and a compensator which transforms the object wave front into an aspherical one, coinciding with the theoretical shape of the controlled aspherical surface, combine the axes of the aspherical surface and the compensator by adjusting the aspherical surface to minimize the axis unsymmetric aberrations and determine the relative position of the axes of the compensator and the measuring base.

EFFECT: increase the accuracy of determining the position of the axis of aspherical optical elements, improve the processability of assembly, increase the range of dimensions of controlled aspherical elements and the nomenclature of controlled optical elements.
