Abstract (2. Language): 
In this study, the optical anisotropy of the photosensitive polymer films was studied as a function of exposure time of linearly polarized ultraviolet (UV) laser light. The anisotropy of the polymer films is due to the photoinduced intermolecular effect under the influence of the UV light. The photoalignment mechanism was investigated on the polymer films by using twisted nematic liquid crystal structures. Twisted nematic liquid crystal structures were examined by a polarizing microscope.
Abstract (Original Language): 
Bu çalışmada ışığa duyarlı polimer filmlerin optiksel anizotropisinin çizgisel kutuplanmış morötesi lazer ışığının uygulanma süresine göre değişimi incelendi. Bu tür polimer filmlerin anizotropisi morötesi ışığın soğurumu sonucu oluşan ışık etkimeli moleküler etkiden ileri gelmektedir. Polimer filmlerdeki fotoyönelim mekanizması bükümlü nematik sıvı kristal yapılar kullanılarak araştırıldı. Bükümlü nematik sıvı kristal yapılar polarize mikroskopla incelendi.
