Abstract

It is suggested to neasure nodal poser distribution in fiber with the aid of conputer generated optical elenents, called aodans. Nodans are Batched to orthogonal nodes and cause transfornation of nodal poser distribution to intensity distribution in a focal plane. The theoretical calculation sere carried out of aodan's coupler transfer function and the particular nethod is suggested of its coding into phase - only function. Belevant optical techniques sere provided, the experinental results are reported for the specific case of Gauss-Laguerre nodes in graded-index fibers. The nethods, sorked out, are shosn to be applicable in fiber optic sensors.
