In memory of Professor Gallieno Denardo, ICTP Italy

Optoelectronics, employing lasers, optical spectroscopy and imaging techniques, provide many low-cost solutions in constructing research equipment, which enables advanced studies also in low-resource settings. In particular, many applications to the highly relevant fields of environmental monitoring, ecology, agriculture, food safety and medicine become possible. Spectroscopic approaches include absorption and fluorescence monitoring. Narrow-band laser sources are useful for gas monitoring, including pollution studies, whereas broad-band light-emitting diodes are sufficient for condensed matter samples. Based on activities along these lines, pursued during 40 years by the author, examples of “realistic” approaches to equipment and applications are given, including studies of crops, food stuffs, air and water pollutants, flying insects, as well as human diseases. © Anita Publications.
