1. A method for chemical signature resolved detection of a concealed object within a system, the method comprising: a. irradiating the system with a plurality of electromagnetic radiation of a specific wavelength around the object; b. capturing a Raman scattered radiation from the object at 4π angles and/or 4π planes around the system, wherein the Raman scattered radiation is captured in steps of at least 0.1 degree with reference to an initial position of capture around the object; c. obtaining a plurality of profiles from the captured component of the scattered electromagnetic radiation; d. filtering the profiles to obtain a chemical signature specific to the object; and e. resolving the chemical signatures to detect the concealed object; wherein, the step of detection includes determination of the shape, size and location of the object.
