Claim 0:
1. An apparatus, comprising:
a modulator configured to receive incident electromagnetic (EM) radiation at a substantially fixed frequency generated by one or more EM radiation sources, the incident EM radiation comprising continuous-wave EM radiation, the modulator configured to impart a sequence onto an amplitude, a phase, or both of the incident EM radiation to generate modulated EM radiation, the modulated EM radiation comprising continuous-wave EM radiation;
a receiver configured to:
receive reference EM radiation at the substantially fixed frequency generated by the one or more EM radiation sources, the reference EM radiation comprising continuous-wave EM radiation;
receive reflected EM radiation from an optical system responsive to the modulated EM radiation;
generate interfered EM radiation responsive to the reference EM radiation and the reflected EM radiation; and
generate a continuous interferogram responsive to the interfered EM radiation.
