Paper Abstract

The interest in liquid crystal devices for photonic non-display devices has grown recently due to their mature quality and the continuous improvement of their speed combined with the rising nanoscale and optoelectronic technologies. Of particular interest is their application in imaging systems as compact devices to manipulate the wavefront, wavelength, phase or polarization. Recently we have been developing variety of specially designed LC devices integrated into imaging systems for specific spectro-polarimetric imaging applications using small number of LC devices. These included: (i) wide dynamic range tunable filters for hyperspectral imaging and frequency domain optical coherence tomography, (ii) discrete narrowband tunable filter for multispectral imaging, (iii) compact polarization rotator for polarimetric imaging, (v) wideband achromatic waveplate for polarimetric camera, (vii) polarization independent LCFP tunable filter, and lately (vii) single LC retarder for hyperspectral imaging. In this report we shall present the main concepts of these devices and their functionality into spectro-polarimetric imaging systems such as in skin cancer diagnosis, and imaging oximetry [1-4].
