Three-dimensional partial coherent holography by a digital micro-mirror device (Conference Presentation)
Author(s): Yi Xue

Paper Abstract

Stimulating multiple neurons simultaneously in brain is an important strategy to study neuronal networks. We propose a novel method to generate three-dimensional stimulating patterns using a Digital Micro-mirror Device (DMD). The DMD is placed in conjugate image plane. The projection pattern on the DMD changes dynamically and synchronized with a pair of galvomirrors in the conjugate plane. The three-dimensional holography is generated by 4-D control of light field (DMD controls x, y, and galvomirrors control k_x,k_y). This novel method is able to generate three-dimensional distributed illumination patterns much faster than the previous methods using Spatial Light Modulators.
