Abstract

The new fiber vortex sensor for supersensitive temperature measurements requires using special ways of a computer processing. In the given paper, it is revealed and studied one from the possible ways of an image conversion of an interference helix into an intensity field with an edge dislocation. A helix rotation transfers into an edge dislocation rotation. An experimentally observed phase shift is recorded as an orientation angle of the edge dislocation axis. It is estimated experimental errors.
