Abstract
We present an optical system for stereoscopic color imaging by using a
single-pixel detector. The system works by illuminating the input scene with a sequence
of microstructured light patterns generated by a color digital light projector (DLP). A
single monochromatic photodiode, synchronized with the DLP, measures the light scattered
by the object for each pattern. The image is recovered computationally by applying
compressive sensing techniques. The RGB chromatic components of the image are
discriminated by exploiting the time-multiplexed color codification of the DLP. The
stereoscopic pair is obtained by splitting the light field generated by the DLP and
projecting microstructured light patterns onto the sample from two different directions.
The experimental setup is configured by simple optical components, a commercial
photodiode and an off-the-shelf DLP projector. Color stereoscopic images of a 3-D scene
obtained with this system are shown.
