Street Spectra

Turn your smartphone into a scientific instrument to analyze lamps colors and their spectra using a diffraction grating.

Aim

A database is gathered at Epicollect5 and classification is done at Zooniverse. The results of both actions will allow scientist to study the effects of the change on technology into LED of streetlamps.

How to participate

There are 2 ways of participate:

Gathering data: To take pictures of the street lamps and their emission spectra, volunteers should use a diffraction grating on top of their smartphones’ camera. These images are uploaded to Epicollect5. https://five.epicollect.net/project/action-street-spectra

Classifying pictures: Volunteers are asked to identify a light source, frame its spectrum and classify the lamp by its technology. Zooniverse is home for this part of the project: https://www.zooniverse.org/projects/actionprojecteu/street-spectra

Needed equipment

To participate gathering data, volunteers should use a 500 lines/mm diffraction grating on top of their smartphones’ camera to take pictures of the street lamps and their emission spectra.

A diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions so the emerging coloration is a form of structural coloration associated to any light source.

To participate classifying pictures a device with Internet conexion is needed.
