Methods for using laser light to detect multiple hidden objects inside random scattering media are discussed. It is shown that the resolution of objects that are upstream relative to the incoming laser source is lowered by the presence of objects further downstream. A scanning method is introduced which uses weighted shadow patterns of objects at fixed locations to 'mask' one section of the detection region, so that objects in the unmasked region can be located by a scanning technique. It is found that the method is very sensitive to random noise, but this noise sensitivity can be reduced through a scanning method where a weighted, double-rod configuration is used for scanning.
