Abstract:
A measurement system includes semiconductor light sources generating an input beam, optical amplifiers receiving the input beam and delivering an intermediate beam, and fused silica fibers with core diameters less than 400 microns receiving and delivering the intermediate beam to the fibers forming a first optical beam. A nonlinear element receives the first optical beam and broadens the spectrum to at least 10 nm through a nonlinear effect to form the output optical beam which includes a near-infrared wavelength of 700-2500 nm. A measurement apparatus is configured to receive the output optical beam and deliver it to a sample to generate a spectroscopy output beam. A receiver receives the spectroscopy output beam having a bandwidth of at least 10 nm and processes the beam to generate an output signal, wherein the light source and the receiver are remote from the sample, and wherein the sample comprises plastics or food industry goods.
