Abstract

We present a single-pixel spatial frequency domain imaging (SP-SFDI) system where a single DMD (digital micromirror device) is used to modulate simultaneously the sinusoidal pattern for the spatial frequency sampling and the spatial sampling patterns to achieve spatial resolution. The detection system is therefore simplified to the point where it is replaced by an integrating sphere (IS) with a photodiode as a bucket detector. The characterization capabilities of this system are verified by imaging the absorption and reduced scattering coefficient of an inhomogeneous turbid media slab and of several moles of the forearm.
