Abstract:
1. A method for detecting a presence of one or more objects in a turbid medium, comprising: illuminating, by a light source, at least a portion of the turbid medium with incident light having at least one predetermined wavelength which interacts with the one or more objects contained in the turbid medium differently than the incident light interacts with the turbid medium; measuring, by one or more light detectors, light that emerges from the turbid medium; detecting and locating, by a processor, the one or more objects located within the turbid medium based on an Optical Imaging Independent Component Analysis (OPTICA) of the emergent light from the turbid medium; and extracting three-dimensional location information about the objects from the processor, wherein the incident light includes at least two different wavelengths, measurements are made at different wavelengths to obtain at least two signals I
