Abstract: An optical system for imaging. The optical system includes light emitting diodes to provide light of predetermined wavelengths. The optical system further includes a charge-coupled device to receive the light emitted by one or more light emitting diodes and reflected by an object for fluorescence imaging of the object. The optical system additionally includes a broadband light source to provide broadband light. Furthermore, the optical system includes a spectrometer to receive the broadband light emitted by the broadband light source and reflected by the object for visible-near infrared-shortwave infrared spectroscopy of the object. Additionally, the optical system includes a hyperspectral camera to receive the broadband light emitted by the broadband light source and reflected by the object for hyperspectral imaging of the object as well as a controller coupled to the light emitting diodes, the broadband light source, the charge-coupled device, the spectrometer and the hyperspectral camera.
