Ibrahim Abdulhalim: Liquid Crystal Devices for Photonic Applications
Source: Soft matter seminar
Recently we have been developing a variety of specially designed LC devices integrated into imaging systems for specific optical imaging applications with emphasis on 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, (vii) single LC retarder for hyperspectral imaging, (viii) annular spatial light modulator, and (ix) optically addressed spatial light modulators. In this lecture the main concepts of these devices and their functionality into imaging systems will be presented such as in skin cancer diagnosis, road and security camera enhancement, information extraction from archaeological items, surface plasmon imaging biosensors, night vision, and full field optical coherence tomography.
