    • The present invention discloses a compact optical spectrometer setup which removes the necessity of embedding into the spectrometer a wavelength dispersive element (prism or grating) and provides higher spectral resolution together with smaller dimensions than conventional portable spectrometers. Incident light, which is defined by a single spectrum, passes through optical band-pass filter (5), optically diffusive element (4), optical filter with spatially non-uniform transmission characteristics (3) and is detected at optical sensor (2). Optical sensor (2) consists of large number of pixels (>le6) with each pixel being subjected to differently transformed spectrum of light incident on band-pass filter (5). Spectrum of incident light is then calculated at controlling device (PC) from signal measured at each pixel and spectral responses matrix whose elements correspond to signals measured at each pixel for each wavelength (in the wavelength range of interest) and are obtained using calibration by a wavelength tuneable monochromatic light source.

    • A Fourier transform infrared spectrometer includes a beam splitter (22), end mirrors (21, 23), one of which is scanned, and detectors (32) detecting the interfered light at the two outputs of a beam combiner (25), which is the same optical element as the beam splitter (22). Time records of detector samples are transformed by Fourier transform to obtain the corresponding spectra. The detectors (32) are sampled alternately in time and the samples subsequently interleaved to provide an increased effective sampling rate. The detectors (32) may be masked by color filter mosaics so that each pixel of each detector is sensitive only to one color of light, and the spectra obtained from pixels detecting different colors may be concatenated.

    • An integrated circuit for an imaging system has an array of optical sensors (40), and an array of optical filters (10) each configured to pass a band of wavelengths onto one or more of the sensors, the array of optical filters being integrated with the array of sensors, and the integrated circuit also having read out circuitry (30) to read out pixel values from the array of sensors to represent an image, different ones of the optical filters being configured to have a different thickness, to pass different bands of wavelengths by means of interference, to allow detection of a spectrum of wavelengths. The read out circuitry can enable multiple pixels under one optical filter to be read out in parallel. The thicknesses may vary non monotonically across the array. The read out, or later image processing, may involve selection or interpolation between wavelengths, to carry out spectral sampling or shifting, to compensate for thickness errors.
