Gerchberg-Saxton algorithm. The hologram, φ(r), is generated in the SLM plane, thus shaping the input Gaussian laser beam into a desired state, which is projected onto the trapping plane. \({\mathcal{F}}\) denotes the Fourier transform. \({\mathcal{F}}^{ - 1}\) is the inverse Fourier transform. After several iterations the resulting hologram converges to a hologram that generates multiple optical traps with equally distributed intensity
