Abstract
Apparatus for measuring spectra from one or more samples, the apparatus including a reference waveguide that receives illuminating radiation used to illuminate at least one sample, at least one sample waveguide that receives sample radiation at least one of reflected from and transmitted through a respective sample, an optical system that spatially distributes radiation from each of the waveguides based on a frequency of the radiation, and focuses radiation from the optical fibres into an imaging plane and an imaging device that captures an image of the focused and spatially distributed radiation from the imaging plane so that the image includes respective spectra from each of the waveguides.

Apparatus for measuring spectra from one or more samples, the apparatus including:
- a) a reference waveguide that receives illuminating radiation used to illuminate at least one sample, wherein the illuminating radiation is at least one of:
- i) natural light;
- ii) solar radiation;
- and,
- iii) a non-artificial source of illumination;
- b) at least one sample waveguide that receives sample radiation at least one of reflected from and transmitted through a respective sample;
- c) an optical system that:
- i) spatially distributes radiation from each of the waveguides based on a frequency of the radiation;
- and,
- ii) focuses radiation from the optical fibres into an imaging plane;
- and,
- d) an imaging device including a sensor that captures an image of the focused and spatially distributed radiation from the imaging plane so that the image includes respective spectra from each of the waveguides.
A method of measuring spectra from one or more samples, the method including:
- a) using a reference waveguide to receive illuminating radiation used to illuminate at least one sample, wherein the illuminating radiation is at least one of:
- i) natural light;
- ii) solar radiation;
- and,
- iii) a non-artificial source of illumination;
- b) using at least one sample waveguide to receive sample radiation at least one of reflected from and transmitted through a respective sample;
- c) using an optical system to:
- i) spatially distribute radiation from each of the waveguides based on a frequency of the radiation;
- and,
- ii) focus radiation from the optical fibres into an imaging plane;
- and,
- d) using an imaging device including a sensor to capture an image of the focused and spatially distributed radiation from the imaging plane so that the image includes respective spectra from each of the waveguides.
