Classification: CPC G  H | IPC H

Claim 9:
10. An apparatus, comprising:
a receiver configured to:
generate interfered electromagnetic (EM) radiation responsive to reference EM radiation and reflected EM radiation, the reflected EM radiation received from a system under test responsive to modulated EM radiation provided to the system under test, the reference EM radiation and the modulated EM radiation including continuous-wave EM radiation; and
generate a continuous interferogram responsive to the interfered EM radiation; and

control circuitry configured to:
provide a sequence to a modulation signal source to generate the modulated EM radiation responsive to incident EM radiation;
digitize the continuous interferogram to obtain a digitized continuous interferogram; and
extract phasors corresponding to different delays responsive to applying one of the sequence or a complex conjugate of the sequence to the digitized continuous interferogram.
