Imaging through highly diffusive media is challenging because of the extensive spreading of light propagation in both time and space. The most advanced technique utilizes an expensive time-of-flight imaging system. Here, we present a simple and efficient approach for computational diffuse optical tomography. A typical CMOS camera captures the transmission light through an object buried between two thick diffusive media. Multiple illumination points provide more information, allowing reconstruction of the hidden object at a higher quality than computational time-of-flight diffuse optical tomography. The demonstration shows a low-cost diffuse optical tomography with high accuracy and low computational complexity.
