Abstract
Apparatus for analyzing, identifying, or imaging a target is configured to avoid and/or prevent nulls that may occur periodically during a terahertz sweep. Exemplary apparatus may utilize a second harmonic lock-in amplifier to generate an error signal used to adjust a DC bias of a phase modulator to maintain an in-phase relationship between beams to avoid nulls in an output signal during frequency sweeping.
