dc.description.abstractMalus (1809) and Beer-Lambert (1729) laws can be combined to separate birefringence and dichroism contributions in IR hyperspectral imaging. This is achieved by using two optically aligned polarisers for the highest transmittance. By rotation sample between the two aligned polarisers, spectra are taken at several angles for a better fit. This method is shown to resolve orientation of sub-diffraction patterns which are ~50 times smaller than the diffraction limit of 5:1 μm (at the wavelength 3.3 μm). Application potential for very different fields ranging from microscopy of bio- and pharmaceutical materials (silk and paracetamol) to satellite imaging of ocean waves with altimeter at K∝ band of 35.75 GHz or 8.39 cm wavelength will be discussed. © 2019 Society of Photo-Optical Instrumentation Engineers (SPIE).en_AU
