What is it about?
The work describes ways how to pattern light in the focal space of an imaging system into designed spatial structures through acousto-optic spatial light modulation. To this end, we describe numerical algorithms to derive suitable acousto-optic holograms from wanted focal light patterns.

Why is it important?
Fast switching between patterns of structured focal light is essential to a recent method of functional neuro-imaging named "3D Custom-Access Serial Holography" (3D-CASH). In 3D-CASH (Nat Meth 19(1) doi: 10.1038/s41592-021-01329-7) a laser beam scans a 3D neural circuit of interconnected neurons by random-access to trace the information transfer in distributed neuronal networks at high temporal resolution.
