A Fourier transform infrared spectrometer includes a beam splitter (22), end mirrors (21, 23), one of which may be scanned, and at least one detector (32) detecting the interfered light at one of the two outputs of a beam combiner (22), which may be the same optical element as the beam splitter (22). Time records of detector samples may be transformed by Fourier transform to obtain the corresponding spectra. The pixels of detector (32) may be sampled alternately in time and the samples subsequently interleaved to provide an increased effective sampling rate. The at least one detector (32) is masked by a color filter mosaic so that each pixel is sensitive only to one color of light, and the spectra obtained from pixels detecting different colors may be concatenated. |
