Polarimeters/ellipsometers are important tools in a wide range of fields, including remote sensing, material characterisation, radar, and biomedical research. We have recently developed and demonstrated a polarimetry technique based on the total internal reflection of light in a glass cone, utilising the polarisation dependence of Fresnel reflection. This technique offers true broadband one-shot polarimetry in a compact design without moving parts. We will outline the underlying scientific principles, fidelity and efficiency, associated applications in two-photon microscopy (developed as QuantIC projects) and give an outlook on our future polarimetry development.
