PROBLEM TO BE SOLVED: To provide a compact spectrometer.SOLUTION: A spectrometer 10 for measuring a spectral signature of an object comprises fringe generating optical member 12 for use with a camera 65 and a processor. The fringe generating optical member 12 is formed of a front optical member 45 and birefringent optical member. The front optical member 45 comprises a diffuser 75 adapted to receive light from the object. The birefringent optical member is adapted to receive light from the diffuser 75 and generate interference fringes. The camera 65 is adapted to receive the interference fringes and the processor generates the spectral signature of the object. This spectrometer 10 is an improved Fourier transform spectrometer suitable for use with digital cameras, such as cameras found in mobile devices 90.SELECTED DRAWING: Figure 1 |
