We propose and experimentally validate a new hyperspectral camera based on the Fourier-transform approach.Two delayed replicas of the optical eld entering an imaging system are produced by the Translating-Wedge-BasedIdentical Pulses eNcoding System (TWINS).1 This device is a common-path birefringent interferometer thatcombines compactness, high delay precision, long-term stability and insensitivity to vibrations. The TWINS scansthe phase delay between the two replicates along many optical cycles. The replicas produce, upon recombination,a high contrast interferogram in each pixel of the detector. An appropriate Fourier transformation of the datasetproduces spectrally resolved images that exhibit high contrast and spatial resolution only limited by the lensand the sensor. The main features of the system in terms of spectral resolution, contrast and bandwidth will bepresented. Examples of application in conservation science will be also reported.
