IMAGING THROUGH SCATTERING MEDIA WITH INTENSITY MODULATED INCOHERENT SOURCES

Imaging through scattering media is a significant challenge in computational imaging. Recently, a breakthrough technique based on speckle scanning was proposed with outstanding imaging performance. However, the dense angular scanning of the incident-laser beam leads to a lengthy scanning process. In this paper, we propose a method based on compressive sensing (CS) to accelerate the data acquisition process. A new imaging system is proposed which adopts mutually incoherent laser beams as light sources and the intensity of each beam is modulated to perform CS measurement. High-resolution fluctuation of the total fluorescence can be well reconstructed from CS measurements with the learned dictionary as basis function. Experimental results show-that the proposed method can reduce nearly 70 percent of the data acquisition complexity without impairing the imaging quality.
