Abstract: The technology disclosed uses extreme beam shaping to increase the amount of energy projected through an AOD. First and second expanders and are described that are positioned before and after the AOD. In one implementation, the optical path shapes energy from a source, such as a Gaussian laser spot, deflects it, then reshapes it into a writing spot. In another implementation for image capture, rather than projection system, the disclosed optics reshape a reading spot from an imaged surface to a high-aspect ratio beam at an AOD exit, subject to deflection by the AOD. The optics reshape the radiation relayed by the high-aspect ratio beam through the AOD to a detector. Since light can travel in both directions through an optical system, the details described in terms of projecting a writing spot onto a radiation sensitive surface also apply to metrology sweeping a reading spot over an imaged surface.
