研究目的
To propose an active hyperspectral imaging system operating in mid-infrared (MIR) band to obtain simultaneously large amounts of spatial and spectral information on the samples, and to evaluate its capacities.
研究成果
The preliminary results of an active hyperspectral imaging system operating in mid-infrared spectral range are presented. The system allows the MIR active imaging spectrometer to analyze large samples with a field of view up to 5 cm diameter. The spectra of averaged zones of plant leaves was obtained, and will be help to characterize health status of different plants before using image processing techniques to find spatial signatures of samples.
研究不足
Noises associated to the source, to thermal variations of the scene, and to the detector. Speckle effects can be observed on the picture. An intensity drift of the background can be observed during MIR measurement.
