ABSTRACT

It has been experimentally demonstrated that an optical vortex produced using the bending of the glass plate with the aid of a load distributed over a finite distance of the upper surface of an optical glass plate is nearly canonical. It has been found that the generated dislocation of the phase front deviates from a pure screw dislocation toward a mixed screw-edge dislocation by no more than ~10%.

    У цій роботі експериментально показано, що оптичний вихор, утворений за допомогою згинання скляної пластини при навантаженні, розподіленому вздовж скінченної відстані на верхній поверхні оптичної скляної пластини, є майже канонічним. Ввиявлено, що утворена дислокація фазового фронту відхиляється від чистої гвинтової дислокації у бік змішаної гвинтово-крайової дислокації не більше ніж на ~10%.

    Ключові слова: оптичний вихор, оптичне скло Ф1, напруження згину
