Patent Images
1. A scanner, comprising:
- an optical device to receive an incident light beam at an angle of incidence, the optical device having disposed therein;
a first deflector to deflect the incident light beam towards a first direction, the first deflector comprising;
a first prism having a first geometry;
at least a second prism having a second geometry different from the first geometry;
a second deflector to deflect the first deflected light beam towards a second direction; and
a lens array disposed in or on the optical device to direct the incident light beam towards the first prism.

Abstract
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.
