Chirp-Pulse Terahertz Range Profiling

Abstract

Terahertz (THz) range profiling is investigated for several cm-size metal targets. Aperiodically-poled lithium niobate crystals are used to generate a chirp-pulse THz signal, which is used to probe several targets. The reflected waveforms from different targets show distinctive features that permit differentiation of the targets. Several additional research tasks required prior to implementation of this detection concept into a prototype system are identified.
