The use of optical spectroscopic methods for quantitative composition measurements in process control is increasing rapidly and the use of imaging spectroscopy for visual inspection and piece sorting is growing even faster. A number of different optical configurations are in use today and many more are being developed to accomplish the wavelength selectivity needed in spectroscopic methods. The development of compact and rugged spectrometers has been one of the major tasks of the optical measurements research team at VTT Electronics. Some of the techniques developed will be presented in this paper.
