1. A method for selectively stimulating a plurality of light-responsive neurons in a sample, the method comprising:
irradiating a sample comprising a plurality of light-responsive neurons with a plurality of holographic images that are each configured to stimulate one or more light-responsive neurons in the sample, wherein the holographic images are created by light projection system that includes:
a plurality of light sources;
a plurality of optical adjustment components;
a plurality of spatial light modulators;
a controller;
a processor; and
a computer-readable medium comprising instructions that, when executed by the processor, cause the controller to:
operate the light sources, optical adjustment components and spatial light modulators to generate and display a plurality of holographic images, wherein light beams from the light sources are combined by orthogonal polarization;
direct each of the holographic images to a projection location; and
project the holographic images onto the sample at a rate greater than or equal to 1 kHz.
