Fotodiyot Dizi Boyutunun Görünür Işıkla Haberleşme (VLC) Performansına Etkileri

Bu çalışmada görünür ışık haberleşme sistemlerinde fotodiyot dizisi kullanımının haberleşme performansına etkileri incelenmiştir. Optik verici kısmında farklı dalga boylarında ışıma yeteneğine sahip yeni nesil power LED’ler ve farklı açılı lensler; optik alıcı kısmında ise görünür ışık bandında ışığa duyarlı PIN fotodiyotlardan oluşan bir algılayıcı dizisi, opamplı karşılaştırma devresi ve ortalama gerilim izleyici bloğu bulunmaktadır. Tasarlanan haberleşme sistemiyle LED akımının büyüklüğünün, lens açısının değerinin, optik verici ile optik alıcı arasındaki mesafenin veri transfer hızına etkileri incelenmiştir.

Effects of Photodiode Array Size on Visible Light Communication (VLC) Performance

In this study, the effects of the use of photodiode arrays in visible light communication systems on communication performance are investigated. In the optical transmitter part, there are new generation power LEDs with different wavelengths and lenses with different angles; in the optical receiver part, there is a sensor array consisting of photosensitive PIN photodiodes in the visible light band, a comparator circuit with an opamp and an average voltage tracking block. With the designed communication system, the effects of the magnitude of the LED current, the value of the lens angle
