green tea spectral data

The hyperspectral detector is the SisuCHEMA - SWIR hyperspectral imaging system from Specim, Finland. The system parameters are set as follows: spatial sampling resolution of 640 × 640 pixels, exposure time of 6.8 ms, frame frequency of 50 Hz, wavelength range of 970 - 2577 nm, number of bands of 288, and resolution of 8 nm. The spectral data of 336 equal - quantity dry green tea samples were measured using this instrument.
