Design of solid-state electro-optic transmission scanner

To improve the performance of the opto-mechanical scanner used for IR imaging system,a new kind of design method for fully solid-state electro-optic scanner was presented,which had no movable elements,and then serial kinds of their configurations were discussed.The scanner mainly consisted of scanning array,coupling waveguide and control circuit.Its principle was that the light signal can be transmitted by controlling each scanning units on scanning array orderly and coupled in IRFPA by coupling waveguide.The scanning array divided the full images into equal pieces,the coupling waveguide coupled light signal of different positions in IRFPA,and the control circuit controlled the states of each scanning units.The scanner has some merits,such as fully solid-state structure,smaller bulk,lighter mass,compatibility,semiconducor manufacture techniques similar to that of IRFPA,potential abilities to integrate with detectors or some other parts of infrared imaging system.
