A series of novel wide range displacement sensors based on polarized light detecting technology is presented. The sensors include a displacement-current comparator and a servo comparison displacement sensor. Special structures and technologies are introduced to the sensor systems to solve the optical problems, such as the nonlinearity, the light source drift etc., and realize wide range measurement. The designing, assembling, and testing results of the prototypes of sensors are described. The testing results of the prototypes show that the novel sensors based on polarized light detecting technology have good linearity, and wide range measuring ability.
