Smartphone Spectrometry

The ubiquitous smartphone contains millions of times more computing power than was used to send the Apollo spacecraft to the moon. Increasingly, scientists are repurposing some of that processing power to create low-cost, convenient scientific instruments. In doing so, these measurements are edging closer to being feasible for citizen scientists and under-funded professionals, democratizing robust … Continue reading Smartphone Spectrometry

A smartphone-based UV spectrometer

In our new paper we report on some novel tech that uses the sensor in a smartphone for ultraviolet spectroscopy. It is low cost and based entirely on off-the-shelf components plus a 3-D printed case. The system was designed with volcanology in mind - specifically the detection of atmospheric sulphur dioxide, but may also have … Continue reading A smartphone-based UV spectrometer
