Otani　Laboratory

　Our laboratory is mainly focused in two main research fields: Polarization engineering implementations and Optomechatronics. By fundamental research on polarization, Stokes and Mueller sensing techniques, we are interested in engineering implementations related to obtain high speed, high accuracy or spatial distribution measurements. In relation with the Optomechatronics implementations, works has been developed related to light driving actuators/manipulators, interferometry and non-contact shape measurement techniques.
