Data on Electrical Engineering Education Reported by Researchers at University of Lisbon (Low-cost spectrograph based on a WebCam: a student project)

By a News Reporter-Staff News Editor at Education Letter -- Investigators discuss new findings in Electrical Engineering Education. According to news originating from Lisbon, Portugal, by VerticalNews correspondents, research stated, "This work describes the implementation of a low-cost spectrometer produced with common objects and proposed as a pedagogical students' project. This task aims to introduce the theme of image detection and to stimulate the students to develop skills in the field of optics and photonics."

Our news journalists obtained a quote from the research from the University of Lisbon, "The performance of the developed spectrometer was tested in the characterisation of several sources such as light emitting diodes (LEDs) operating in the visible spectral range and the results were compared with those obtained with a commercial spectrometer. Foreseeing a possible application, the spectrometer was used to calculate the emission (x,y) colour coordinates following the Commission Internationale d'Eclairage (CIE) definition of the LEDs. The calculated (x, y) colour coordinates using the built spectrometer compare well with those calculated using the emission data measured using a commercial spectrometer, pointing out that the proposed methodology provides good resolution and precision in the calculation of the CIE colour coordinates."

According to the news editors, the research concluded: "This project was offered with success in 2010 to students from the Optoelectronics unit of the Physics Engineering Masters degree at Aveiro University, Portugal."
