Abstract

Napretkom tehnologije i pojeftinjenjem procesa proizvodnje, poluvodički izvori svjetlosti poput svjetlećih ili laserskih dioda postali su jeftini i sveprisutni. Počele su se pojavljivati prve ideje o mogućnosti komunikacije preko moduliranih poluvodičkih izvora svjetlosti. U ovom radu objašnjen je i realiziran jednostavan komunikacijski sustav s vidljivom svjetlosti. Analizirane su osnove rada takvih sustava te prednosti, nedostatci i glavne razlike u odnosu na radiofrekvencijske sustave. Naposljetku, sustav je implementiran i ostvarena je stabilna komunikacija na frekvencijama 100 kHz i 1 MHz.

Abstract (english)

The advancements in the field of technology and cheapening of the production process have made semiconducting optical sources such as LEDs or LDs cheap and ubiquitous. Consequently, ideas about the possibility of communication via modulated semiconducting optical sources began to appear. In this paper, these ideas were explained and a simple communication system using visible light was described. System basics were analyzed and their characteristics were compared to those of radio-frequency systems. Finally, the system was implemented and a stable communication at frequencies of 100 kHz and 1 MHz was achieved.
