Abstract
An analyzing apparatus and method generates a laser beam at a target. The Raman scattered photons from the target are collected and used to generate a Raman spectrum indicative of the composition of materials associated with the target, such as components of chemical or biological weapons. In one embodiment, a laser beam is generated with two streams of photons, the photons of one beam being entangled with the photons of the other beam. One stream is then directed at the target and only the other beam is analyzed to obtain said Raman spectrum. Alternatively, the scattered photons from the second beam are also analyzed and the results are correlated for greater efficiency and accuracy.
