Confocal Single-Pixel Imaging

Obtaining depth-selective images requires gating procedures such as spatial, nonlinear, or coherence to differentiate light originating from different depths of the volume interest. Nonlinear pulsed excitation sources and probes, limiting easy usage. Coherence also broadband interferometry requiring specialized stable setups. Spatial can be used both for fluorescence reflection geometry various thus has least requirements on hardware, but still use a pinhole which makes it difficult photography widefield imaging schemes. Here, we demonstrate that utilize single digital micromirror device (DMD) simultaneously function dynamic illumination modulator automatically synchronized array obtain depth-sectioned images. Utilizing multiplexed measurement advantage single-pixel imaging, show depth ballistic confocal pixel scheme utilized through glare multiple scattering where conventional fails recover clear due saturation random scattered noise.
