Spectroscopy system of diffuse reflection and method for obtaining a diffuse reflection spectrum

摘要

a spektroskopiesystem separates the diffuse reflexionskomponente a reflexionsspektrums (remissionsspektrums) of the reflective reflexionskomponente using a remote fernblendenfilters. the surface of the sample is in a focal plane of an optical system are arranged.the optical system forms an image on the surface of the sample, which is an image of the far feldblendenfilters covers. the optical system forms the surface of the sample either in the same or in a different distance feldblende.from the surface of the sample reflected energy, which in the distant feldblende focused, keeps the image information over the image of the filter, while below the surface of the sample reflected energy is not necessarily image information on the image of the filter is maintained.since the energy of the surface of the sample spiegelnd is reflected and the energy of below the surface diffuse reflections, the reflective component of the reflexionsspektrums spatially separated from a part of the diffuse reflexionskomponente in distant feldblende and filtered out.the now filtered reflexionsspektrum contains diffusely reflected energy to the detector of a spectrometer is addressed.
