Abstract
Summary form only given. We have shown that THz imaging can detect powders inside envelopes at a concentration of 80 milligrams/cm/sup 2/ and that in a carefully controlled experiment classification algorithms can be used to differentiate between different types of powders. We have also presented images of bacteria spores inside envelopes and will demonstrate the performance of classification algorithms in detecting B. thuringiensis.
