Abstract(s)
As medidas óticas vieram oferecer novas formas de determinar distâncias, deformações
ou vibrações através de métodos mais precisos e de maior alcance. A evolução tecnológica tem
permitido uma melhoria significativa de vários componentes, nos quais se incluem os óticos.
Assim, o desenvolvimento de métodos de medida essenciais é crucial para acompanhar o
avanço tecnológico.
Nesta dissertação, são estudados os três métodos de medida básicos – a triangulação,
a telemetria e a interferometria, abordando as suas principais aplicações, vantagens e
desvantagens, e fundamentando teoricamente cada um dos métodos. Ao longo do trabalho
mostram-se resultados de rotinas de simulação para cada método. Para o método da
triangulação efetuaram-se duas experiências que demonstram o funcionamento do método na
medida de distâncias e superfícies.
Para o método da telemetria, estudaram-se montagens experimentais para aplicar o
método da telemetria por impulsos e telemetria por comparação de fase na medida de distâncias.
Deste modo, pretende-se construir a base de um futuro desenvolvimento de métodos
mais complexos.
Optical measuring systems came to offer new ways to determine distances, deformations or vibrations through more accurate and greater range methods. Technological progress has allowed a significant improvement of several components, including the optical ones. Thus, the development of essential measurement methods is crucial to keep up with technological advances. In this dissertation, the three basic methods of measurement are studied - triangulation, telemetry and interferometry, covering their main applications, advantages and disadvantages, and theoretically substantiating each of the methods. The results of simulation routines for each method are shown along this work. For the triangulation method we made two experiments which demonstrate the functioning of the method in measuring distances and surfaces. For the telemetry method, experimental setups were studied to apply the method of pulse telemetry and phase comparison telemetry to measure distances. Thus, it is intended to set up the basis for the future development of more complex methods.
