Two dimensional optical scanning image system
An ultra high speed miniature two dimensional electro-optic image acquisition system uses prisms of varying geometries to control the amount of horizontal deflection and a Bragg grating to control the amount of vertical deflection. A collimating lens array and a Gaussian profile Bragg grating help confine the beam diameter of the deflected light beam. A separate prism further bends light into the vertical direction. A spherical lens focuses light onto a photodetector array for display.
