Abstract: A compact spectrometer system comprising an improved detector is provided herein. The spectrometer system herein disclosed can comprises a filter, a Fourier transform optical element, and a detector. The detector can comprise a custom detector having a shape that corresponds to the pattern of light incident on the detector. The custom detector may comprise a plurality of separate detection areas, each area configured to detect a portion of the light pattern incident on the detector. The custom detector may comprise a material capable of detecting wavelengths in the short-wavelength infrared (SWIR) range. The custom detector may be configured to require a relatively low number of electrical connections such that it may be implemented using standard, low-cost electronic packaging techniques. An improved, custom detector as described herein can provide the functionality of a two-dimensional pixel array detector while being relatively simple and inexpensive to manufacture.

Abstract: A hand-held measurement device for appearance analyses includes a measurement array which comprises a number of illumination means for applying illumination light to a measurement field in at least three illumination directions and a number of pick-up means for capturing the measurement light in at least one observation direction. The illumination directions and the observation directions lie in a common system plane. At least one pick-up means is embodied to spectrally gauge the measurement light in a locally integral way, and at least one imaging pick-up means is embodied to gauge the measurement light in terms of color in a locally resolved way. The spectral pick-up means and the locally resolving pick-up means are arranged such that they receive the measurement light reflected by the measurement field under the same observation conditions and in particular from the same observation direction.
