Hinalea Imaging’s range of hyperspectral cameras are based upon a small Fabry-Pérot interferometer positioned in front of the camera sensor which acts as a tuneable spectral band-pass filter. When operated in hyperspectral mode, this filter enables images to be captured with up to 300 spectral bands in the VIS/NIR range. The filter bandpass is approximately 4nm across the VIS/NIR range and, as all sensor pixels are used for imaging, these cameras provide both high spatial and spectral resolution at an affordable price point. The Fabry-Pérot interferometric filter allows the possibility of hyperspectral cameras operating in the UV, VIS/NIR as well as the SWIR wavelengths. Importantly, the Hinalea cameras can also be operated in either hyperspectral or multispectral modes. In many spectral imaging applications, data is spectrally sparse, and it is sufficient to acquire only a subset of spectral bands. The HinaLea system can be programmed to scan a subset of bands, and this subset can be dynamically controlled based upon the object to be imaged. Resultant scan times can be shorter and generate smaller data sets, saving time and money. In multispectral mode these cameras have been shown to work at video rates with real-time classification based upon spectral features.
