Measuring the properties of colloidal PbS quantum dot thin films using differential photocarrier radiometry technology

AIP Advances
Colloidal quantum dots have been widely applied in various optoelectronic devices such as solar cells, photodetectors, and light emitting diodes. The measurement of carrier dynamics not only allows the study of the passivation quality of quantum dot ...

Field and Airborne Spectroscopy Cross Validation—Some Considerations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Field spectroscopy is increasingly used in various fields of science: either as a research tool in its own right or in support of airborne- or space-based optical instruments for calibration or validation purposes.

Processing and Assessment of Spectrometric, Stereoscopic Imagery Collected Using a Lightweight UAV Spectral Camera for Precision Agriculture

Remote Sensing, 2013
Imaging using lightweight, unmanned airborne vehicles (UAVs) is one of the most rapidly developing fields in remote sensing technology. The new, tunable, Fabry-Perot interferometer-based (FPI) spectral camera, which weighs less than 700 g, makes it ...
