Hyperspectral imaging

4MP hyperspectral data-cube acquisition of hand: true color RGB rendering picture, spectral plots of Hb versus HbO spectra’s within oxygenated and deoxygenated skin where finger blood circulation is tied by rubber band.

Orthophoto hyperspectral aerial images of large test field of soybean cultures in Brazil: the color image is augmented with spectral features information recolored images to show where specific variations within crop cultures (e.g. disease pattern) are being observed to support precision agriculture decisions – Courtesy of GAMAYA.

SNAPSCAN hyperspectral imaging VNIR with imec LS 150+ bands in 470 – 900nm range enables robust classification of various different pharmaceutical pills with similar colors but different chemical formulation.

Pseudo NDVI recolored imaged from the SNAPSCAN hyperspectral imaging VNIR range camera showing vigor of vegetation on a cloudy autumn day from imec tower building in Belgium. Fresh grass, soil, sky and autumn leaves spectra are plotted for comparison.

Ripeness of avocados can be easily extracted thanks to their level of reflectance in the NIR wavelength bands. Spectral imaging of food is already being deployed for the food quality grading of fruits and vegetables like apples, kiwis, cherries, avocados, etc...

Snapshot hyperspectral imaging of retina: HSI camera is mounted onto a Topcon fundus camera to extract oxygenation of the different vessels of the retina. Oxygenation maps of the retina are key in supporting early diagnostic of several eye and brain diseases such as Age Macular Degeneration (AMD), Diabetic Retinopathy (DR) and Alzheimer Disease (AD) – Courtesy of Northwestern university.

Hyperspectral imaging in SWIR range enables robust classification of various different white plastics types including PET, PVC, PE, PMMA, PS, PP, etc…

Snapshot hyperspectral imaging of the human brain under guided surgery: the HSI camera is mounted onto a Carl ZEISS surgery microscope. Reconstructed color / Hb / HbO / HbT maps of the brain are key in supporting accurate detection of brain tumors as well as to study hemodynamics of severe epilepsy patients – Courtesy of Polytechnique Montreal.
