Abstract: A rasterization method of patterns with periodic components for SLMs is presented, comprising obtaining (S10) of an original pattern, having a periodicity. A first pattern main period is determined (S21). Image area and a first pitch of imaged elements are obtained (S31). The original pattern is scaled (S41) by a first raster scaling factor. The scaled pattern is cropped (S51) to comprise a first integer number of repetitions of the pattern items presenting a periodicity in the first direction that is covered by the image area, giving a rasterized pattern adapted to the intended pattern generator. The rasterized pattern is associated with data representing the first scaling factor. A writing method comprises obtaining of the rasterized pattern. Elements of the SLM in the pattern generator falling outside the rasterized pattern are set to be disabled. The rasterized pattern is written with an optical scaling to a target surface.

A second plurality of digital pattern descriptions is then generated, and corresponding corrected digital pattern descriptions are generated using the trained reinforcement learning agent, thereby generating training data.

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.
