1. A detection method comprising:
- directing radiation such that the radiation is incident upon a target, the radiation containing a component having a first polarisation;
detecting radiation which is scattered from the target;
directing further radiation such that the further radiation is incident upon the target, the further radiation containing a component having a polarisation which is different from and non-orthogonal to the first polarisation;
detecting further radiation which is scattered from the target; and
analysing the detected radiation to any of detect and identify an object.

Abstract
A detection method comprising directing radiation such that it is incident upon a target, the radiation containing a component having a first polarisation and a component having a second orthogonal polarisation, detecting radiation which is scattered from the target, and analysing the polarisation state of the detected scattered radiation to determine whether the target includes an object.

21. A detection system comprising:
-
at least one transmitter configured to direct radiation containing a component having a first polarisation such that the radiation is incident upon a target, and configured to direct further radiation such that the further radiation is incident upon the target, the further radiation containing a component having a polarisation which is different from and non-orthogonal to the first polarisation, wherein the detection system further comprises at least one receiver and at least one detector configured to receive and detect radiation which is scattered from the target and configured to receive and detect further radiation which is scattered from the target, and a processor which is configured to analyse the detected radiation to any of detect and identify an object. - View Dependent Claims (22)
