Improvement of performance in FFH-OCDMA systems by using strong apodized fiber Bragg gratings
(SPIE-INT SOC OPTICAL ENGINEERING, 2004-01-01)
This paper shows simulations of an all-fiber fast optical code division multiple access communications system (OCDMA), using strong apodized fiber Bragg gratings (FBGs) arrays as passive encoding-decoding devices. Auto and ...
Low-cost detection of RC-IED activation signals in VHF band
(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01)
The proliferation of Radio Controlled Improvised Explosive Devices (RC-IED) is a growing threat around the world. The ease of construction and low cost of these devices are transforming common things in lethal tramps. The ...

Analysis of a developed analog trilateration system of impulsive sounds
(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01)
A characterization study is made from a trilateration system for impulsive sounds, in which theoretical analysis and experimental results are presented. This system uses an analog trilateration method, avoiding to implement ...
Optical design of a high-power LED-based solar simulator
(SPIE-INT SOC OPTICAL ENGINEERING, 2016-01-01)
The optical design of a High-Power LED based Solar Simulator was made in order to reach the AM1.5G spectrum standards. An optical model of the light emitted by the LEDs was made and used for spectral intensities calculations ...
