Recording the vortex beam parameters in turbulent atmosphere
No full textIn the second part of the paper the Hartmann sensor model is introduced into design diagram; it allows determining its influence on optical system operation accuracy and optimizing the device parameters. In the closing paragraph the accuracy of detecting the optical vortex in turbulent medium using the sensor is compared with the accuracy of the results of the ideal optical system operation
Recording the vortex beam parameters in turbulent atmosphere
No full textBased on the methods of the numerical experiments the authors study the possibility of determining the characteristics of vortex radiation expanding in turbulent medium. To obtain the estimation results given in the first part of the paper the parameters are determined using gradients of phase distribution of light field; the ideal optical system is considered
