1. New technique for the implementation of digital demodulation of fiber optic gyroscopes / Implementação de uma nova tecnica para demodulação digital de sinal de giroscopio a fibra optica
Gyroscopes are devices used to measure angular orientation, being extensively employed for guidance, navigation and stabilization. Among the many types of gyroscopes, IFOG (Interferometer Fiber Optic Gyroscope), based on Sagnac effect, is the most interesting solution due to its high sensitivity, resolution, reliability, small size and EMI immunity. The pres

2. Sistema para interrogaÃÃo de redes de bragg utilizando laser EDF sintonizando mecanicamente / System for interrogation nets of Bragg using lazer EDF syntonized mechanically
Este trabalho descreve sistemas para interrogaÃÃo de redes de Bragg multiplexadas, atravÃs de varredura espectral do sinal produzido por um laser a fibra dopada com Ãrbio com cavidade linear. A sintonia do laser à obtida pela traÃÃo da rede de Bragg que atua como um dos refletores da cavidade. O sistema mecÃnico de traÃÃo consiste em um atuador pie

3. A broadband imaging system for research applications
We have developed a compact, computer-piloted, high sensitivity broadband imaging system for laboratory research that is compatible with various detectors. Mirror optics allow application from the visible to the far infrared spectral range. A prototype tested in conjunction with a mercury cadmium telluride detector exhibits a peak detectivity of 6.7×1010 cm
