Recent
integration of imaging and spectroscopy with contiguous spectral analysis,
hyperspectral imaging is introduced. This is the technology as analytical tool
for non-destructive analysis. With the
hyperspectral imaging, even the composite distribution could be analysed.
The spectral range is 400 to 2500 nm within which images are captured with contiguous and narrow spectral band. It includes more than 200 spectral bands including some bands in infrared and ultraviolet with visible spectrum. This extra contiguous spectral information is used to classify object with higher accuracy.
The basic idea behind the spectral imaging is variation of amount of radiation reflected, absorbed and emitted is function of wavelength that is frequency for a given material.
This imaging has huge applications in food quality and safety measure. This spectral imaging could be used for the detection of bruise on citrus like fruits and on apple. This technology has usage on meat quality maintenance.
