AOIS – Hyperspectral chamber with tunable acousto-optical filter
AOIS – Acoustic-Optical Imaging Spectrometer - is a new hyper-spectral instrument developed by Proambiente, capable of obtaining simultaneous spectral-spatial information to investigate wide areas. The AOIS system allows sequential acquisitions of an object at different wavelengths. The series of frames form a hyper-spectral cube, in which x and y axes represent the observed scenario, while the depth z represents the wavelength. From the analysis of the hyper-spectral cube, it is possible to obtain the high resolution spectrum of each point (pixel) of the observed area.
