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.
