Episode 100: The optical oscilloscope
The optical oscilloscope is one of the most visited instruments in the Faraday Museum (Técnico – Alameda campus). Manufactured in 1925 by Siemens, it shows visitors how the image of a beam of light appears and how it is possible to observe fast signals synchronised with the electrical network. This technology was at the origin of the technology that, more than 100 years ago, gave medicine the possibility of recording the movements of the heart in two dimensions on a sheet of paper – the appearance of the electrocardiographs – and may play an important role in the field of harnessing solar energy.
