Rapid SLM Design for Grid-Free Multispot Positioning in 2D and 3D with a Modified Gerchberg-Saxton Algorithm

• A single-plane FFT-based algorithm which optimizes a defocused field corresponding to a desired spatial configuration of focused spots is presented. The defocused target field allows for grid-free spot positioning in 2D and 3D.
