Study on deflection characteristics of electro-optic scanners with special geometrical shapes

In this paper, three types of scanner which their width are varied with parabolic, hyperbolic and exponential functions are studied. The equations of deflection angle and ray trajectory of three types of electro-optic scanner are given and their deflection properties are investigated by numerical analysis. The deflection characteristics and sensitivities are compared to each other. It is helpful for the design of electro-optic scanners with fine performance.
