dc.description.abstractLos sistemas VLC (Visible Light Communication), emplean como transmisores LEDs (Light Emitting Diodes) y como receptores, fotodetectores. Esto es debido a su alta velocidad de repuesta y sirven para comunicaciones ópticas no guiadas. Existen diferentes tipos de fotodetectores, los más conocidos son los fotodiodos de juntura tipo PN, PIN y APD.En este trabajo se presenta la caracterización de un sensor LTF (Light To Frecuency) TSL235R-LF el cual consta de un fotodiodo tipo PIN y un convertidor de corriente a frecuencia. Este dispositivo genera una señal cuadrada de amplitud constante, ciclo de dureza del 50% y la frecuencia resultante es una función de la potencia óptica incidente. En nuestro experimento se usaron como fuente, emisores LED RGB y se pudo observar que la frecuencia generada por el sensor aumenta o disminuye linealmente dependiendo de la potencia óptica incidente. Se notó que, para iguales potencias ópticas detectadas, a diferentes longitudes de onda (rojo, verde y azul), la frecuencia de salida del sensor LTF es diferente, lo que resulta de gran interés para la distinción de símbolos en el formato de modulación CSK en sistemas VLCspa
dc.description.abstractVLC systems (Visible Light Communication), use LEDs (Light Emitting Diodes) as transmitters and photodetectors as receivers. This is because its high speed of response and they are useful for wireless optical communications. There are different kind of photodetectors, the most common are the PN, PIN and APD photodiodes. In this dissertation we present the characterization of an LTF (Light to Frequency) TSL235R-LF Sensor which consists of a PIN type photodiode, and a current to frequency converter. This device generate a square signal with constant amplitude, 50 % duty cycle and its frequency is a function of the incident optical power. In our experiment, we use as a light source an RGB LED for transmitting and we notice that the generated frequency by the LTF increases or decreases linearly, depending on the incident optical power. We noticed that, for the same optical powers detected, with a different wavelength (red, green and blue), the output frequency of the LTF sensor is different. This fact is of great interest in order to distinguish symbols in CSK modulation formats on VLC systems. eng
