Phase singular point localization of vortex beam using optical correlation
Abstrak
The study of optical vortex beams has garnered significant attention due to their wide-ranging applications. These beams exhibit a phase singularity and accurately identifying the location of the singular point is crucial for various vortex-based applications. This study introduces a novel method for localizing the phase singularity of optical vortex beams using a hybrid optical correlator. In contrast to machine learning-based techniques, the proposed approach eliminates the need for complex architectures, reducing computational demands and facilitating real-time implementation. The method demonstrates robust performance under varying conditions, including different contrast levels and aberrations such as astigmatism.
