According to embodiments of the present invention, an ultra high speed miniature image acquisition system based on a scanning light beam for use with clinical endoscopic imaging applications, for example, is disclosed. In one embodiment, the image acquisition system may include a horizontal beam deflector disposed in an electro-optic polymer waveguide may disperse an incident light beam into a spectrum in a horizontal direction. A vertical beam deflector disposed in the waveguide and optically coupled to the horizontal beam deflector may deflect the horizontally dispersed spectrum in a vertical direction. An electrical charge may be applied to the electro-optic polymer.
