Advanced spectral analyzes are aimed at identifying objects. A characteristic parameter, on the basis of which it is possible to draw conclusions about the composition and physicochemical properties, is reflectance. Based on the analysis of spectral curves, it is possible to carry out detection without the need for direct contact with the tested object.
We conduct advanced spectral research based on aerial photographs and material acquired using a spectral signature test bed. We determine such indicators as, among others:
Thanks to the determined indicators, it is possible to determine the health of organic matter, water content or the content of impurities.
Thermal analysis – equipment
We provide reference data, for analysis of aerial photographs, satellite photos and those taken in unmanned space missions, enabling identification of objects recorded in the ultraviolet, visible and infrared ranges. We have three spectrometers that allow us to measure spectral signatures in the range from 200 nm to 25,000 nm for liquids, suspensions and solids. We also have a device for testing the content of NPK in the soil and a fluorimeter determining the condition of plants.
We have constructed a specialized stand for acquiring multispectral images of the tested material, equipped with:
- multispectral camera (range 460-1100 nm),
- narrow band interference filters,
- markers with reflectance <5%,
- markers with reflectance >95%,
- an illumination system with characteristics similar to the spectrum of the Sun. We also have an XRF spectrometer with an X-ray range for identifying elements in a given substance and determining their quantity.
As part of the HESOFF project, we have built a Quercus multi-sensor platform imaging different ranges of electromagnetic radiation.
Potential application areas of the Quercus platform:
- environmental monitoring (air and water pollution, illegal dumps, post-mining waste, spontaneous combustion of a mine slag heap);
- biodiversity monitoring;
- snow cover monitoring;
- modern agriculture (yield optimization, crops monitoring and harvest planning);
- spatial planning (land cover, degree of urbanization);
- crisis management (prediction and minimization of natural disasters);
- national security (border and coastline protection, weapons detection);
- mass event security (detection of dangerous situations in crowds, detection of hazardous substances).
