In opdracht van het Groninger Instituut Archeologie van de Rijksuniversiteit Groningen en de Doggerland projectgroep is onderzoek gedaan naar de effectiviteit van de Reflectance Transformation Imaging (RTI) en fotogrammetrie. Deze twee technieken zijn toegepast op kaakfragmenten met gebitselementen uit …

Spectral imaging has many applications, from methane detection using satellites to disease detection on crops. However, spectral cameras remain a costly solution ranging from 10 thousand to 100 thousand euros for the hardware alone. Here, we present a low-cost multispectral camera (LC-MSC) with 64 LEDs …

To enhance our understanding of forest carbon sequestration, climate change mitigation and drought impact on forest ecosystems, the availability of high-resolution annual forest growth maps based on tree-ring width (TRW) would provide a significant advancement to the field. Site-specific characteristics, …

Soil organic carbon (SOC) prediction from remote sensing is often hindered by disturbing factors at the soil surface, such as photosynthetic active and non–photosynthetic active vegetation, variation in soil moisture or surface roughness. With the increasing amount of freely available satellite data, …

Er wordt bewuster omgegaan met de bodem om deze, op dit moment en voor de toekomst, niet nadelig te beïnvloeden. Voor agrarisch ondernemers is dit van groot belang. Hierbij ligt de focus op de chemische, fysische en biologische gezondheid van de bodem. Dit onderzoek is afgebakend tot de chemische gesteldheid …

Abstract A setup is designed and constructed to perform specular reectance spectroscopy on an enzymatic reaction, while simultaneously monitoring the heat produced by the reaction using a FLIR camera. The spectrum of ethanol was recorded using two MCT detectors and showed clear overlap with literature …

Single Fiber Reflectance spectroscopy (SFR) can be used to determine tissue optical properties such as scattering and absorption. The SFR technique employs a semi-empirical modal, which contains a parameter that is dependent on the fiber numerical aperture, NA . However, the NA is a wavelength dependent …
