Image processing of optical vortex and determination of OAM

Abstract

This study aims to analyse the transverse spatial profile of the intensity of optical vortex patterns which have been produced by using fork hologram and spatial light modulator. The properties of intensity distribution has been investigated by using image processing technique. The results will be very useful to understand the change of the intensity profile and the value of orbital angular momentum of optical vortex patterns which are obtained experimentally.

Optik vorteksin görüntü işleme ve OAM tayini

Abstract

Bu çalışma, optik girdap desenlerinin yoğunluğunun enine uzaysal profilini analiz etmeyi amaçlamaktadır. Çatal hologram ve uzaysal ışık modülatörü kullanılarak üretilmiştir. Yoğunluk dağılımının özellikleri görüntü işleme tekniği kullanılarak incelenmiştir. Sonuçlar deneysel olarak elde edilen optik girdap desenlerinin momentumunu, yoğunluk profilinin değişimini ve yörünge açısalının değerini anlamak için çok faydalı olacaktır.

Keywords

• görüntü işleme
• yörüngesel açısal momentum
• bükümlü ışık
